Hi Marilois, and welcome to planDisney!
If you ask me, you are already on your way to experiencing a memorable
Walt Disney World Resort vacation! The fact that you have an idea of when you would like to visit, the rest of your planning process will be super fun.
If you happen to make a vacation reservation and a better incentive becomes available, you can modify your current reservation using your
My Disney Experience account or call Disney Resort Hotel Reservations at (407) 939-1936 so that a cast member will be able to assist with the change. It would be wonderful if the
Disney Dining Plan makes an appearance, but in the meantime, the dining plans are temporarily unavailable. If they become available, yes, you can modify your reserved vacation. Please note that if you modify a vacation package, you can make changes or cancel your vacation without penalty 30 days before arrival. On the other hand, if your reservation consists of only a resort hotel reservation, you can make those changes up to 24 hours before your arrival.
Please let us know if you have additional questions.
Have a magical time!
Raquel
