Michele,
I think that if you pick the right plan for you, it is a great way to save money. What I would recommend you do is look at
the plans that are available (Quick Service, Standard, Deluxe) and see which is best for you.
A quick summary is as follows;
For each plan, you get the following number of meals/snacks per evening that you have in the hotel
Quick-Service Dining Plan: 2 quick service meals, 2 snacks
Standard Dining Plan: 1 table service meal, 1 quick service meal, and 1 snack
Deluxe Dining Plan: 3 table service meals, and 2 snacks
Based on what you have said so far, I would doubt that the Deluxe would be good for you, but the Standard might be a really great way to save money.
I am glad to handle any follow-up questions!
Have a magical vacation!
