Welcome to
planDisney, Katharine!
A split stay between three
Disney Resorts Collection hotels sounds truly magical. My family is actually planning on doing a split stay between two Disney Resorts on our next
Walt Disney World trip. It's like having multiple vacations in one!
The refillable mugs are a great option for your trip. These give you unlimited refills for the entirety of your stay on various Coke products, hot chocolate, coffee, and tea. You can use these at the Disney Resorts, but not the theme parks (a common mistake). Not only do these refillable mugs work out at a decent price if you use them for the entirety of your trip, but they make nice souvenirs. My wife and I purchased them on our 5th year anniversary and got more than our money's worth in coffee refills alone!
You should have no problem using your mugs at the different Disney Resorts during your split stay. However, you might want to mention to a Cast Member your final checkout date when you purchase the mugs. If you run into any problems at the second (or third) Disney Resort, I'm sure someone can always fix it for you.
I hope that's helpful, Katharine! I just know that you'll have an enchanting trip. Enjoy everything on offer for the
50th Anniversary Celebration.
TTFN, ta-ta for now!
Mike
