Great review Kathy! we were in London 2 weeks ago and agree that the AC is not so great. It was very hot. we saw Billy Elliot which was great altho there is one scene involving a puppet of MArgret Thatcher and a song to go with that is a little off-putting. She is not very well-liked, at least in the theater! I also agree that London Walks is a lot of fun for very little $. We did jack the ripper with Donald who is "the" expert on the ripper. Didn't get to do the Beatle Walk---Oh well, next time.We also did a combo Thames cruise and London Eye champagne flight which was worth the price because you skip the line. You can buy that online from London Eye web site. London is a great city with lots to do and see.
