Ok so I just make my FP reservations for Jan 29th but already there were no available FP for Anna & Elsa so I booked Cinderella as a replacement but how do I keep checking to see if a FP for Anna & Elsa becomes available without messing up my current FP selections? I would cancel my Cinderella one if I can get A&E. Also whats the chances of getting in to see A&E if we just go straight there? Thanks!
