Meanwhile, the companion in some ways of the other review I just wrote, of the Palace of the Stock…read moreExchange in Portugal, this tour is definitely of a gaudy palace built by royalty with a whole *lot* of stolen gold and jewels, so I was glad to learn that it isn't *still* owned by the royal family, it's owned by the state and mostly used for state functions, other than its purpose as far as tourists are concerned, being a museum of a fraction of the riches Spain owns (and not a coincidence, presumably, that they also built a museum of *more* of the riches owned by Spain, on display right next door, for a combined, reduced price.) The self-guided tour is worth it if you like seeing a bunch of super ornate architecture, furniture, artwork, etc. We got snippets of the actual tour as we passed each other at various points - I was happier being able to walk through the route at our own pace, which took about an hour.
I felt sorry for the people whose tickets were for any time the following day, though, as it was randomly closed all day the next day we were in Madrid a few months ago, which I gather isn't an altogether rare thing to happen, that they take reservations and then close last minute. We got in in the nick of time, it seemed.
By the way, if you have bags, you do have to leave your bags downstairs in a locker at a small additional fee. It was small enough I do remember exactly how much it even was, though, so it clearly wasn't a big deal.
