Hey there Ashley and welcome to planDisney.
Woah! It looks like y'all are going to have a huge trip in less than two weeks. Four rooms could be up to 20 people. Talk about an awesome Walt Disney World Resort vacation!
You can update the reservation of Guests staying at a
Disney Resorts Collection hotel however, this must be done with a Cast Member over the
phone or at the hotel reception desk. It should not take very long. To do it over the phone you will need the primary Guest of both reservations on the call. If on property please arrive at the hotel reception desk with the Guest who is being moved as well as the primary Guest of each room. If you are using MagicBands, you will need those as well so the information can be updated.
planDisney Pro Tip: With large groups dining can be a real burden, especially at
Quick Service locations where you need to find tables. I recommend using
Mobile Food & Beverage Ordering through the
My Disney Experience Mobile App for those
restaurants that participate in the service. This allows you to pre-order your meals and not stand in line. Once your designated time arrives, head to the restaurant and let them know you are there through the app. Everyone can search for tables and when the order is finally ready, you will receive a notification. No need to stand in line and then search for a place to sit while you balance a food tray.
Ashley, I hope this information helps you and the rest of your crew have an enchanted visit to the "Place Where Dreams Come True." Please feel free to
write me back directly with any follow-up questions.
Enjoy making many Magical Memories.
