Hi there, Kaylee!
Welcome aboard planDisney. Thanks so much for stopping by as you prepare for your time at Disney Castaway Cay. In no time at all, you'll be setting sail for fun and adventure aboard Disney Cruise Line!
If you'd like to purchase a cooler bag with water bottles on Castaway Cay, you'll want to use your Key to the World Card or
Disney Band+ to charge the purchase to your onboard account. You can then use your preferred form of payment to settle your account. You may have listed a credit or debit card as your preferred form of payment while completing your online check-in process for your sailing, but you are welcome to drop by Guest Services during your cruise and pay for a portion of any onboard charges with cash or a Disney gift card, too.
I hope that information helps. I love leaving my wallet behind in the stateroom as I head off for a day of fun at
Castaway Cay! It's one less thing to think about as I ride bikes with my family, snorkel with stingrays, or lounge in a hammock.
Have a relaxing time, Kaylee! Bon Voyage!
