Hi Ilana,
Welcome back to the Disney Parks Moms Panel, and thank you for your question. First, let me give you three chEARs for your choice of resorts! Both
Disney’s Art of Animation Resort and
Disney's Polynesian Village Resort are spectacularly themed, full of truly magical details, and wonderful places to call home. On top of gorgeous resorts, you're spending fifteen nights in The Most Magical Place on Earth? You sure know how to vacation, Ilana!
Earlier this year, my family and I had a long split stay, where we changed resorts three times. We LOVED it! It was such fun to explore brand new resorts and we left feeling like we had really traveled “the World.” On that trip, we each had a Resort Refillable Mug, and the mugs worked at all three resorts. When you refill your mug at the beverage islands, there’s an electronic screen that will tell you when the mug expires, which I find really convenient.
Ilana, I do recommend asking the Cast Member at the dining location where you first purchase the mugs to ensure the mugs will be active for the entire length of your stay. I’ve also seen mixed answers about this, so I think asking on site is going to be your best bet for getting up-to-date and accurate information. Also, be sure to hang on to your receipt, as it will be helpful if you encounter any trouble using the mugs when you switch resorts. Walt Disney World Cast Members are so helpful and knowledgeable, so don't be afraid to ask them any questions or ask for assistance at any time.
Have so much fun counting down to your vacation, and please come back and see us if you have any more questions! It’s so much fun to help a fellow Disney dreamer.
Wishing you a magical vacation,
Robyn
