Hi David,
The Villas at Disney's Grand Floridian Resort and Spa look amazing! I can hardly wait to stay at this beautiful new resort.
Disney's new MyMagic+ program is currently being tested at Walt Disney World. When it launches fully, guests will be able to use the MagicBands for so many parts of the Walt Disney World experience, including purchasing food and merchandise, entering resort rooms, and getting into the theme parks. It is such an exciting program!
I do not have concrete information to respond to your specific question about currently existing tickets and how they will be integrated when the MagicBands are widely available. My best advice for you is to watch to see if MyMagic+ is fully launched before your vacation. The best place to do this is by monitoring the
Disney Parks Blog. Then, call 407-W-DISNEY (407-934-7639) to ask them if it is possible to add your theme park tickets can to your MagicBands.
Have a wonderful time planning your vacation, David, and please do not hesitate to ask if you have any further questions!
