We will be going to WDW over Easter. I know that reservations to the special events such as Hoop dee doo and Poly Luau are a necessity, but do you need to make dinner reservations at ALL restaurants prior to your vacation, or can you just walk in and place your name on a list? I know Easter is a very busy time, but I hate to over-plan, and then be locked into a dinner reservation which may not coincide with that day's plans. Thanks.
