For our upcoming trip at the end of August we bought date based tickets for a Sunday through Sunday, but we may actually end up using them for Saturday through Saturday (going to the parks a day early). Will there be a problem when we show up on the Saturday a day before the date range we based the tickets on? Will we need to pay a differential if the incremental Saturday was more expensive that the Sunday that we are dropping? If it is date dependent is there an easy way to figure out what the difference is? Do we need to go to guest services to make an adjustment and if so, do we have to do this before the first Saturday or just sometime in our trip?
Thanks for the help!
