Hi Kerri!
Under 50 days until sailing! Wahoo! I love the Fantasy and your itinerary is one of my favorites too! Your family is truly in for a vacation of a lifetime with Disney Cruise Line.
Here are a few suggestions worth looking into for your time ashore. On Costa Maya, the
Dolphin Encounter is very close to the ship, offered at a great price, and only about 1 1/2 hr. long. I think your princesses would love interacting with these amazing mammals. After your adventure, I recommend heading back to the ship to enjoy it as your destination. If your family loves the beach, then the
Jungle Beach Break is a nice option too! On Cozumel,
Dolphin Discovery Cozumel is fantastic if you don't choose the Dolphin Encounter in Costa Maya. If you want a little history with some splashtacular fun,
Cozumel Ruins & Beach Tour is another possibility. One last recommendation if your girls enjoy marine life is the
Atlantis Submarine Expedition Cozumel. The underwater sights are spectacular!
Whatever your crew chooses, I know you are going to have a fantabulous time!
Have a magical day and bon voyage!
