Hi Wendy!
How wonderful to hear you are visiting the Walt Disney World Resort so soon! I can almost feel the pixie dust as you are planning the last details of your magical vacation. Hooray!
Disney's All-Star Music Resort does offer a mini-fridge in each of their Guest Rooms, however, there is not a microwave. You will find a microwave available for Guest use in the Intermission Food Court. Should you decide to upgrade your room to one of the
Family Suites at Disney's All-Star Music Resort, you will find the included kitchenette does offer a mini-fridge, microwave and coffee maker.
For your next question, even without purchasing a
Disney Dining Plan, you are able to purchase the refillable resort mugs. My family loves the freedom and taking the mug home as a memento of our last vacation, so we almost always purchase it, even when we aren't using the Disney Dining Plan. You are usually able to find the mugs near the registers at the food court and once activated by the cashiers, you are able to immediately start using them.
Thank you again for visiting us with your great questions and have a magical trip, Wendy. If there is anything else we are able to assist you with, please let us know.
Pixie Dust,
Lauren
