Hi Alice,
Thank you for visiting the Disney Parks Moms Panel with your question.
The Disney Dining Plan is a great way to enjoy the delicious dining options that are available at Walt Disney World Resort.
Credits for the Disney Dining Plans are calculated based on how many nights you stay. So yes, if your visit is for 6 nights, you will have 6 Table-Service credits, 6 Quick-Service Credits and 12 Snacks per person during your stay. These credits are valid from the time you check in until midnight of the day you checkout and you are able to use these credits as you wish.
Since you are planning on using the Disney Dining Plan, I would recommend making sure you make Advanced Dining Reservations to ensure you are able to dine at the restaurants of your choice. Table-Service Dining Locations are very popular and tend to fill up quickly. Guests are able to make
Advanced Dining Reservations online or by calling (407) 939-1947 up to 180 days in advance.
I hope you have a fantastic time at Walt Disney World Resort, Alice. Please let us know if you have any other questions, we are always happy to help.
Stephanie
