Am adding to this because I have just returned from Ewan's second two weeker.
The first week we teamed up with some other mums and kids to go places and one was in a wheelchair. The British Museum has wheelchairs you can borrow at the door of the museum, and to get up the steps at the front there is a little lift.
We wanted to see a show, some of the theatres had no wheelchair access, sadly. However the Dominion, where we went to see We will rock You(the Queen musical) did have a lift down the stairs, although the person has to be able to transfer from the wheelchair to an ordinary seat once in the stalls. Once there,there was a special host because of our disabilities and he couldn't have been nicer. When I said we were worried about getting back to the hospital because you can never find a taxi after the show and asked if he could call one, he did and it was waiting outside afterwards, and was a people carrier so had enough room for us all.it waited around the corner by the stage door and some of the cast came out and said hello to the kids. Also, we paid half price for the tickets because we had a seat free as a carer for each disabled child by showing blue badges or cinema cards(CEA cards). So, a great experience. There is a cafe rouge next to the theatre.
It is worth looking on voucher websites before going as you can find deals for major attractions and restaurants, and money off cinemas etc. One of the best is the two for one by train site if you travel there by National Rail, (you must keep your tickets) you can print out vouchers for two for the price of one for many sights in London such as the zoo, Madame Tussauds, the imax 3d films at the Science museum just to mention a few and even theatre tickets.
