    The main facility in the center

    My daughter had a trial lesson and liked it, so I signed her up for weekly lessons. Every time at the end of the lesson she would complain "arms fell off! " because the activities were intense, but i could tell from the viewing windows that she was having fun through the obstacle courses. The business owner couple are really passionate about what they do, they thoughtfully arranged everything from hardware to software with care to make customer feel welcomed. The facilities are new, clean and flexible, the classes are very time efficient-- kids keep rotating on different items and nobody has time to idle around. Overall we are very satisfied with our experience at USA ninja challenge so far. Kudos to the owner Aman and his wife for doing an excellent job.

    My son and daughter joined the ninja gym last week and absolutely love it! I've seen my daughter's confidence grow in just two sessions when trying new things and it's been amazing. All instructors have been so caring and patient with my kids when they're acting like normal squirrel chasers and running off to something else. They ask every day if it's time for ninja class. Spreading the word because we've had a really positive experience so far.

It's small but a nice spot to spend under an hour. Also finding the entrance was hard because google maps takes you to the wrong main gate.

Because they are working with important stuff pertaining to national security, nuclear materials and other top secret stuff, they won't let the average Yelper in there. But, right outside their front gate is the Discovery Center. The Discovery Center is a small museum that gives you a brief introduction to the lab and what they do. They have hands on and interactive exhibits for children to play with. Most of the exhibits were well maintained. It is an interesting way to spend an hour. The staff, at least on the day were there, was fantastic. Since we were the only ones there, she almost gave us a personalized tour to explain some of the exhibits and talk about the lab and what they do. They have an easy scavenger hunt for children with a nice t-shirt as a prize. They are pretty generous with the scavenger hunt and let children of all ages play. The museum is priced just right for most Yelpers. It is free! It's a nice place, with not a lot of visitors.

    Went to Peek-A-Boo Factory in Livermore on the Sunday before Memorial Day and surprisingly it was…read morenot packed at all, which honestly made the experience way more enjoyable. I was nervous about bigger kids accidentally pushing my baby while running around, but it felt comfortable and manageable the whole time. The slides and play structures were really cool and my little one had such a fun time running around and exploring. I especially appreciated that they have a separate toddler/younger kids area which made it feel safer and less overwhelming. As a parent, I noticed the staff did a good job keeping things organized and the overall environment felt pretty clean. There were also plenty of places for parents to sit while still being able to watch their kids play, which I appreciated. But it's either my hubby, I, or the both of us with my baby the whole time. Parking was easy too and check-in was pretty smooth. I do wish the place was a little bigger, but I also understand indoor playgrounds are probably expensive to maintain and operate these days. Overall, it was a fun experience and my baby left tired and happy which is always a win. Would definitely come back. Just wish there was a location closer to Morgan Hill!

Sophie, our party attendant, was super helpful and made sure we stayed within our timeline. Daniela was also very responsive and answer any questions I had. The facility itself was very clean, there's always someone cleaning. Lots of activities for kids to do and all very safe as well. I would definitely bring my daughter here again and recommend hosting a party here if you're thinking about planning a birthday party.

Unfortunately, the party planning and overall management left a lot to be desired. Before the party, I received an email saying that a coordinator would contact me to finalize the food order, but I never heard from anyone until 2 days of the party even though I sent a follow-up email which I didn't receive a response, which made planning stressful. At the end of the party, fewer children attended than we had originally expected, and our total guest count was still within the overall party limit. Despite that, we were charged extra for additional adults, which was disappointing and didn't feel very customer-friendly. We were also told we had 15 minutes to vacate the play area. While the venue itself is great for open play, I wouldn't recommend it as a birthday party venue based on my experience. The focus seemed to be more on additional charges than on providing a smooth, enjoyable experience for families. I would happily bring my son back to play, but I would choose a different location for future birthday celebrations.

At $80 per child for the most basic package on a weekend I expected a higher level of service. Throughout the party, I had to ask for everything. I had to request water pitchers, ask for a candle and lighter, and no one offered to help cut the cake. The staff didn't offer much help coordinating the event. I've had parties at Pump It Up, where the staff was much more attentive and proactive. I also had an unpleasant interaction with an employee (Scott?). The employee's old white car was parked in front of the facility, with its windows completely down and a cracked windshield, and its alarm went off. The employee came outside, WALKED ON THE HOOD OF HIS CAR to turn off the alarm, and then accused me of hitting his car. My husband and the five children in my car all confirmed that I didn't. After confronting me in the parking lot, he walked back into K1 while I followed behind. I found it very inappropriate for an employee to yell at a customer, especially as they were entering the business. The kids enjoyed themselves, but the overall customer service was not up to my expectations. When I book a party I like to be stress free, otherwise I would just host a party at my own house.

My group participated in the mini golf with neon, and glow in the dark theme. The children had a blast. The kid golf clubs were filthy. I did make a comment to the young staff, it seemed as if they're not cleaned often. There are three bathroom stalls, not enough to accommodate the plethora of children coming. Plus, there was no soap and the second time I escorted the girls to the bathroom there were no paper towels. Are there bathroom checked to replenish these items? The play area was a hot mess two female staff was sitting and talking, later I did see them picking up balls from the ball pit. But no supervision or enforcing rules with the children. Overall the children enjoyed themselves but the lack of staff supervision, dirty equipment, and no soap and paper towels in the female bathroom, I wouldn't recommend.

    Staff was super friendly and helpful. She signed us up for a 30 day membership, using the price of…read moreour daughter's GLOW hour to purchase it (the balance remaining was $0. to be paid). Our daughter can come every day, at any time including GLOW, for free during the 30 days. There are SO MANY zones here, including an iWall (interactive running, dancing, poses, etc), a cycloBEAT (two stationary bikes to race flying through obstacles, racing over water and on streets, etc), Dodgeball, Double Mega Launch (two HUGE slides to go down), Freestyle jump (jump, spin, flip, play), Air court (play basketball, soccer, volleyball and more dodgeball), and Toddler zone (a smaller jump area to run up walls and over obstacles for tots). There is a dinning area and snack bar with various treats and quick eats like pizza and nachos. There is an enclosed open party area to host a birthday, lots of arcade games, clean restrooms, oversized comfy chairs for parents to observe from and massage chairs to pamper while the little play. We will return during the 30 day pass and dependent on the usage we may purchase the annual membership ($259), which is half off a 12 month membership month to month at $43.99 (based on an Extra Play membership). The Basic Play membership is limited at $36.99 and offers 50% off GLOW (vs free as Extra Play). GLOW is a BIG DEAL to our daughter so that's a must have for us to have included. GLOW, at this location, does not begin until 8 PM.With so many other kids playing, our daughter bounced between kids to play with and enjoyed a couple longer than others. At 9:15, majority of the kids our daughter was playing with were gone. With the drastic decline in playmates and the closure of one zone it dampened her spirits. The late start of GLOW will likely be our greatest reason for not becoming members. We tried it on a Saturday this time. We will try again on a Friday to see if there is any difference in play and length of attendance. Overall, such a great experience with updated, modernized play spaces for big and little kids alike.
