Ahoy there, Lynn! What a thoughtful gift that you want to give your grandchildren for their summer vacation!
If they are not at least 18 years old, an Adult can add the Disney Gift Cards to their stateroom account by visiting Guest Services once they board their Disney Cruise Line ship. I have another option for you as well! You can purchase Onboard Credit in advance for them if you have their sail date in addition to their first and last names to enter in the
Onboard Gifts section on the Disney Cruise Line website. You can purchase the Onboard Credit with a major credit card, Disney Gift Card, or Disney Rewards Redemption Card.
The Onboard Credit can be used for Port Adventures, merchandise, and other additional expenses incurred on the ship,
Disney Castaway Cay, or
Disney Lookout Cay at Lighthouse Point. Your grandchildren will receive a card in their stateroom indicating they have Onboard Credit from you. I find purchasing Onboard Credit, even for myself, saves time from standing in line at Guest Services.
Lynn, I hope this answers your question and gets you started with your gift-giving plans. There are other gift options in Onboard Gifts that you may want to consider as well. I hope your grandchildren come back with lots of pictures to show you and memories to share. If you have any other questions, sail back to
planDisney. We are happy to help you and your grandchildren!
Ohana Means Family!
