I'm looking to spend a few days in London at the beginning of April to celebrate my husbands 40th. I have 2 boys 8 & 14. I'd like to do something special but don't really know what. We haven't any experience of London. It would be nice to visit museums and maybe a show. Are there any escorted activities so that we don't waste time finding our way around?
Advice, recommendations and tips gratefully received.
