Hi, Tracey! Your Dining Plan Credits are based on the number of nights you are staying at your resort, not your number of days on your tickets. Your credits are valid from the time you check-in until midnight of the day you check-out. For more information on the Deluxe Dining Plan, click
HERE.
To see a complete list of participating restaurants, click
HERE. This document is very informative and not only lists the restaurants, but lets you know if they are character meals, buffets, if gratuities are included, and more.
Since you have the Deluxe Dining Plan, make sure to make Advance Dining Reservations by calling (407)WDW-DINE. The Deluxe Plan gives you a lot of credits, and you won't want to waste them, so make sure to have your meals planned out. As you are planning, let us know if you need any dining suggestions!
Wishing your princess a magical October birthday!
