Hi Julie!
Welcome aboard the Disney Parks Moms Panel! Your grandson is one lucky boy! He is going to have such an incredible time while sailing the high seas with Captain Mickey! There are so many fun things onboard for kids his age to do! Between the Youth Clubs and Deck Parties, he's going to have an unforgettable vacation with you!
I believe you're inquiring about either the
Blue Lagoon Island Dolphin Encounter Port Adventure or the
Blue Lagoon Island Sea Lion Encounter Port Adventure. If you're inquiring about this particular sea lion adventure, unfortunately, it is only for Guests 8-years old and up. However, I'm happy to tell you that your 6-year old grandson is able to enjoy the Blue Lagoon Island Dolphin Encounter, though! In my opinion, this excursion is so much fun and definitely worth it if your little explorer enjoys meeting and playing with dolphins! The excursion will begin with an orientation led by knowledgeable dolphin trainers before jumping in and interacting with the dolphins. Since your grandson is 6-years old, an adult 18-years old or older will need to be booked on the same excursion with him.
After selecting a particular Port Adventure on the Disney Cruise Line website, you can find the prices listed on the upper right-hand side. Prices are subject to change but currently, the Blue Lagoon Island Dolphin Encounter is $148.00 per person (ages 10 and up) and $133.00 per person (ages 4 to 9). Port Adventures will be charged to your stateroom account once onboard.
Julie, if you were inquiring about a different Port Adventure, please don't hesitate to visit us again! We will be happy to assist you in finding the perfect Port Adventure for you and your grandson to enjoy!
