Hi Rory and welcome to planDisney!
It looks as though your visit to
Walt Disney World is only a few weeks away now - how exciting! Have you started getting your suitcases down from the loft yet?
3 weeks at
Disney's Art of Animation Resort sounds like pure heaven to me! Not only is it home to the largest resort pool at Walt Disney World but, it also means that you'll be able to use one of the most fun modes of complimentary Disney Transportation during your stay - The
Disney Skyliner.
Rory, you can absolutely charge additional meals, snacks, gratuities from any Table-Service meals and merchandise to your room, throughout your stay using either a MagicBand or Key to the World Card which you can set up as a payment method at your Resort hotel Front Desk or during online check-in. You'll also need a 4-digit PIN to use with your
MagicBand or Key to the World Card.
You can stop by the Front Desk at any time to check the balance and/or make payments. When visiting for 3 weeks, I like to do this at least once a week just so that I can keep a check on how much we are spending and make sure that we're on budget for the rest of the trip.
Believe me when I say that it really couldn't be any easier!
I hope that this has answered your question, Rory. Please feel free to re-visit us, here at planDisney, if we can be of any further help with the planning of your trip.
Wishing you a magical holiday filled with memories which will last a lifetime!
Emma
