have just got back from a two week holiday to WDW. Crowds were actually lighter than I expected - 30 - 40 minutes for most rides expect as already mentioned - Mission Space (60 mins), Soarin' (120 mins) RNRC (90 mins) and Splash Mountain (160 mins on the 3rd July).
Hope this helps xx
Welcome to the forums. So very sorry to hear your sad news.
I also would suggest contacting Guest Relations - I am sure they would be able to suggest something for you.
