Jolene,
Yes, and yes!
The
Dining Plan is VERY easy to use. It is all run on your room key. When you are going to eat at a restaurant or get a snack, just hand them your room key and they deduct the appropriate credit from your card, whether it be a table service meal credit, a snack credit, or a quick service credit.
And yes, it is worth it. You just have to pick the plan that is right for you. The Quick Service plan is ideal for families that just do fast food dining. The Standard plan is great for getting a combination of table service meals in, but also some quick service dining as well. That is what my family typically uses. And the Deluxe is for that traveling group that eats a sit-down meal every time, and likes to have all the dining paid for and easy to deal with.
You can see brochures for all of them at the link I posted above.
If you send me any follow-up questions, I am glad to answer them for you!
Have a magical (and delicious) vacation!
