I wasn't keen on doing a river cruise, but this was actually quite nice! We did a one-way trip down…read moreto Greenwich, Home of the Royal Naval observatory.
The cruise did make about three stops on the way down there, which was a little annoying. Because we would go a short distance, dock, take on a few more passengers, go down river, dock again, etc. but once we got going it was very nice. They also do a running commentary about buildings along the waterfront, which was interesting and helpful.
Also appreciated some hints on what to see and do in Greenwich, which was not on our radar screen. But really glad we went there... The observatory was cool, and lots of nice restaurants and pubs. Definitely would recommend this again.
Only downside was at some of the passengers had poor manners... Woman in front of us changed her young child clothing, which I really did not need to see.
