Hi, Katie!
You are going to love Pop Century! It is "totally groovy!" With 4 boys, you are going to really appreciate the awesome food court at this resort.
If you included the Disney Dining Plan in your package, refillable mugs are included for everyone in your party age 3 and over. These mugs can be used for unlimited refills on soft drinks, coffee, tea, and hot chocolate at your resort's food court for your entire stay. Mugs cannot be refilled at other resorts, water parks, or theme parks so just leave them in your room when you leave for the day.
I don't know which Dining Plan you might have, so click
HERE to see what is included with your particular Dining Plan.
Have a great time in Walt Disney World, and
let me know if you have any other questions!
