Hi Amy! How exciting to hear you have a vacation planned at the
Walt Disney World Resort!
One of my favorite things to do as soon as we arrive at our home resort is to pick up our refillable mug. They are so convenient as they allow you to get refills of soft drinks, coffee, hot cocoa, and tea during your visit at various stations located throughout the
Disney Resort Hotels. However, they will not work at
Disney's Typhoon Lagoon or
Disney's Blizzard Beach, since the refill stations at those two locations will not recognize the built-in chip. Mugs at water parks usually come in a different design so they will make a good souvenir, you can use it for decorating purposes at home or to eat popcorn out of, to hold pencils and markers on a desk, etc.
I hope this has been somewhat helpful, Amy. Please come back with more and more questions, if you need to!
See you real soon!
