Hi Francesca,
Thanks for stopping by the Disney Parks Moms Panel with your trip planning question! I'm sorry to hear that you and your roommate may be incompatible.
While you will not be able to move a mattress to the balcony, I have a few other ideas that can help you have a much more restful night. I'm afraid you wouldn't sleep very much if you attempted to sleep outside.
Walt Disney World Resorts do offer rooms that have separate bedrooms. This may be the best option so that both of you can enjoy your vacation and are rested each morning for your park touring. The suites at
Disney's Art of Animation Resort offer a master bedroom type set up with a separate bathroom and door that can be closed to the rest of the suite. Your roommate would then have the choice of a fold-down bed or pull-out sofa bed and a separate bathroom. This would give you both quite a bit of space and privacy. Many of the
Deluxe Villa Resorts also offer multiple bedrooms.
Another great option would be two connecting but separate rooms at any of the
Walt Disney World Resorts. Here you'll have two rooms with a door between them. You can keep the door open during the day, but close it at night for additional quiet time. To request connecting rooms, you'll want to call Walt Disney World at (407) 939-5277. While these types of room requests are not guaranteed, they'll do their best to honor your wishes.
Of course, if you'd like to stay in the same room, the best bet may end up being earplugs or a white noise machine. I'm not sure if either of these would work, but they would likely give you a more comfortable night than trying to sleep outside (with resort noise like transportation and deliveries).
I hope you have a magical vacation!
Kathie
