Hi, Jaynee (I love the spelling of your name!)! This answer is an easy one!
The cost of the regular dining plan for an adult is $51.54 during regular season, but if you're going during a peak travel season, you can add $2 to that cost. For the quick service dining plan, the adult cost is $34.99, regardless of the season.
You don't mention when you'll be traveling, but maybe it's during a free dining period? If you book by May 18th for travel between August 25 and September 29, you may be able to take advantage of the free dining promotion currently being offered. You'll find all the details by clicking

Have a wonderful vacation, Jaynee, and thank you so much for the question!
