Hey there, Lisa. Thanks for stopping by the Disney Parks Moms Panel with your question.
It sounds like you have a really fun trip planned with your adult daughters. I can only hope that when my daughter is that age she'll still want to explore the Walt Disney World Theme Parks with me too. I'm sure those memories will be priceless!
As of right now, a
Walt Disney World vacation package cannot be broken up by individuals sharing a room. Everyone must have the same vacation package details like ticket days and the
Disney Dining Plan. The only way I can see that working for you would be to book two different rooms during your
Walt Disney World vacation. The daughter who is staying 8 nights in a separate room with a separate vacation package and then everyone else in the other room on the other vacation package. Otherwise you'll just need to pay for the extra tickets and Disney Dining Plan for the daughter who won't be staying for everyone else to have it.
The other option would be to forego a vacation package all together and plan your trip al la carte. You would need to book a
Walt Disney World Resort Hotel room and then buy your tickets separately. By doing this, however, you would not be eligible for the Disney Dining Plan.
I know it's not ideal, I'm sorry I don't have better news for you. I do think if all the girls want to stay together an al la carte vacation is the best option for them. If you have any other questions, please do feel free to stop back by and ask. Have fun!
