Hi Uriel!
Thanks for visiting the Moms Panel with your great question.
The
Disney Dining Plan is purchased in conjunction with your Magic Your Way
Vacation Package. As such, it does correspond to the number of
nights
of your hotel stay, not the number of days that you will be on site. You cannot opt to change the plan to be for more, or less credits. Read all about the plan including how it is allocated and used, on pages 1 & 2 of the
2013 Disney Dining Plan.
Since you're staying for 8 nights, you'll be allocated Dining Plan credits
based on that length of stay. These credits are used as you wish, beginning immediately upon your arrival and check-in and expiring at midnight on your departure date.
If you have further questions about a specific plan, or how to use your credits, please feel free to write me back and I'll be happy to assist you! I've used both the regular and deluxe dining plans on all of our family's trips over the past 9 years and I absolutely
LOVE the value, convenience and flexibility they provide.
I hope to hear from you again soon Uriel!
Wishing you a simply Magical time at Walt Disney World!
Kirsten
