Hi, Jeanie!
That is exciting news that you locked in your vacation dates for 2018. Now the countdown to your magical vacation begins!
You can upgrade your "room only" reservation as soon as the 2018 rates are released, probably early summer. You can include all the goodies to make your vacation complete: theme park tickets,
dining plan, and more! Once the rates are posted, simply call a Cast Member at (407)934-7639 to modify your existing reservation.
If you still have your 2016
MagicBands, you are welcome to use them for your future trip. However, guests staying at a Disney Resort hotel are offered complimentary MagicBands with each stay so you are welcome to get new ones - maybe pick some different colors. I suggest getting new ones. While the battery life should be 2+ years on your bands, I prefer to have a back-up just in case.
I am so glad you find the
Disney Parks Moms Panel helpful. It is certainly our pleasure to add a touch of pixie dust to guests' vacations!
Cathy
