We have a touring plan for the MK for two days that includes lunch both days - 1st day at Pecos Bill and 2nd day at The Plaza on Main Street. I've decided to buy 5 vouchers for each meal. We haven't decided where to eat for the other days we'll be there. Can I order the 10 vouchers we need for those days and then order more when we decide where we're going to eat for those days? This is our first trip to WDW in years and I want to be prepared. We'll be going at the end of March.
