Welcome Aboard, Laurel!
Sounds like you're deep in the planning stages for your magical vacation. Booking
Port Adventures and onboard activities is super fun, and helps to get you even more excited about your vacation than you already are!
No need to worry about payment just yet! All of your Port Adventures/Spa Services/Adult Dining, etc. will be booked to your onboard stateroom account. When you complete your Online Check-In at
www.disneycruise.com, you'll have the option to connect a credit card to your shipboard account. You can also elect to make a cash deposit once you board the ship.
On the last day of your cruise, you'll receive an itemized bill of all of your onboard purchases, including Port Adventures. If you've set up your account with a credit card, your charges will automatically be billed to your card. If you use a cash payment, you'll need to stop by Guest Services on the last night to settle your account.
Have fun booking some fun activities for your sailing party, and I hope you have a magical vacation with Disney Cruise Line! - Diane W.
