Hi, Christy!
To double check, I just chatted with a Cast Member who confirmed that
Disney's Coronado Springs does have rollaway beds for a nightly rental fee. However, the number of beds available are limited and offered on a first come, first served basis. You may want to call the front desk the day prior to your arrival to inquire about their inventory.
Upon check-in, stop by the front desk to see if they will be able to supply you with the much desired rollaway bed. As the mom to two teenagers myself, I hope this all works out for you and your kids!
It sounds like your kids will be the perfect age to enjoy
Pandora - The World of Avatar at Disney's Animal Kingdom. If your schedule allows, take a flight on a banshee on
Avatar Flight of Passage. It is truly an unforgettable experience! Sivako!
Enjoy your stay at the beautiful Coronado Springs Resort.
