Sounds like a major party in the works, Jennifer!
It's always fun to share vacation memories with your family and friends. The kids (and the big kids) will surely have a blast out on the high seas.
Once all your individual staterooms have been booked, you'll each be given a cruise reservation number. Take note of all cruise reservation numbers and call the Disney Cruise Travel Desk to have them "link" your reservations together. You can call the DCL Travel Desk directly at 1-800-951-3532. Let them know that you'd like to be seated at dinner together -- you guys will need to decide whether or not you all want to do the 1st or 2nd dinner seating of course. Your dinner seats will either be in one table, or you'll be seated very close to each other in the dining room.
Once your reservations are linked, you'll also be able to view each other's booked activities on the
MyOnline Cruise Activities site. Each guest will be able to view each other plans, which makes it really easy to coordinate onboard activities (ie: Spa time :-)... as well as Port Adventures.
I hope this helps, Jennifer. Please let us know if you have any additional questions to help you plan your upcoming cruise vacation.
Have a great day!
