Hi Samantha,
Welcome back to the Moms Panel! Keep those questions coming. We love helping you with your vacation planning.
The best part of the Disney Dining Plan is that you don't have to over-think about your meal planning. There's no need to figure out spending limits, what entrees are included, or the "proper" way to utilize your plan. Cast members will inform you of what items are eligible for your dining plan when you order. There is usually a special menu offered to you during your table service reservation, and special meals or meal packages offered to guests when choosing a meal at a Quick Service station. For your snacks, feel free to ask cast members what items qualify for your credit, and they will be more than happy to list them for you.
If you would like more information on your Disney Dining Plan, this webpage is very helpful:
2015 Dining Plan. I hope this answered your question, Samantha. If you have any other questions, feel free to ask us at any time.
Have a fantastical Disney day!
