Ahoy, Amy!
Thanks for stopping by the Disney Parks Moms Panel, and congratulations on your upcoming cruise! I can't think of a better way to start the new year than with a cruise on the beautiful
Disney Dream! It's a gorgeous vessel, with lots to see and do - you'll be welcomed aboard like royalty as you step onto the ship!
I'm assuming the Port Adventure you have your eye on is the
Atlantis Dolphin Cay Shallow Water Interaction & Discover Atlantis. My family really enjoyed this excursion on one of our past cruises! I know the wetsuits came in lots of sizes to accommodate all guests. My daughter was five at the time, and there were much smaller children in wetsuits that day. We were also there during the month of January, and it was quite warm the day we visited! The interaction itself only lasted about thirty minutes, and we were in waist deep water.
If you're concerned your daughter will get too cold in the water, you could always dress her in a little rash-guard type top that will cover her arms and shoulders. That way, even under a wetsuit, she would have an extra layer for warmth.
After your dolphin encounter, you'll have an opportunity to view and purchase photographs taken by their professional photographer. Our dolphin photos are some of our favorite souvenirs from that particular vacation!
I hope you and your family have a most magical vacation, and enjoy yourselves at Dolphin Cay! - Diane W.
