Be careful with the moving walkways, we asked for them to be slowed and everytime I've asked I was told with no uncertain terms that they cannot accomadate that. We do travel durning the summer so it is usually very busy, my mom had such a bad experience with the moving walkways she refuses to ride anything now that has a moving walkway and requires a transfer from a wheelchair (she fell on the moving walkway on the Nemo ride after we asked if they could slow it down, was told no but she wanted to try it anyway, she learned her lesson and hasn't tried another one since).
All in all if your daughter is struggling to walk and needs a moving walkway slowed down, if they refuse I highly suggest she doesn't risk it!
