Hiya Louise Karen!
Welcome again to planDisney! We love your questions and are glad to help! Refillable Resort Mugs and souvenir mugs are an obsession of mine. There is not a day where I open my cabinets to not find several cups fall on me as it overcrowded. I just can't stop buying them and have a hard time throwing it out. Maybe for this New Year, I can declutter. (I say this knowing I already think the new designs this year are cute)
This year's Resort Refillable Mugs have an expanded usage area in that they are not only good-to-go at the Resort you are staying at but they work at any
Walt Disney World Resort Hotel Quick-Service beverage station. Unfortunately, they will not work at the water parks. I did confirm this with a Cast Member. I'm sorry that I don't have better news but I would still consider purchasing one if you are planning on visiting a few Resorts or planning to enjoy a refillable beverage while staying at your own Resort. Not all locations have the Coke Freestyle machines but when they do I am obsessed with the Minute Maid Agua Frescas that are only available in these machines. This is what I distinctly remember about my stay at
Disney's Port Orleans Resort- French Quarter. I remember the Agua Fresca and the Mickey beignets from
Scat Cat's Club - Café to be the best part of that trip. Consider taking a trip for a refill and a treat! Trust me, they are delicious. Don't forget the dipping sauces!
I hope this helped and you have a great trip!
Happy Planning!
