I have a reservation for 6 nights in August at Bay Lake Tower. Due to a slight change in plans, we may do 4 nights at another resort with a three night Disney Cruise and cancel the original one. If I cancel my Bay Lake tower reservation and make another one for four of the same days at another resort, will I lose the fast passes that I already have? I'm confused on how this would work and would hate to lose some of them! Any advice on the best way to do this would be appreciated!
