Great to hear from you again, Heather!
That itinerary sounds like a great choice - you've got a nice combination of ports to visit as well as some sea days to really enjoy the majestic Disney Fantasy with your family. And the best part yet - you get to spend time at Disney's Castaway Cay!
There's a good amount of Port Adventures that are available. Disney Cruise offers a variety of choices for all members of the family, depending on what type of activity you'd like to enjoy while you are docked at one of the ports you are visiting. Here's a link to the
port activities listing... on the left pane, you can click on Caribbean as your Destination, and right below that, you can check on the name of the ports that you are visiting. You can filter your searches and limit it to age specific activities and even the activity type. For new places that you've never been to, it's always nice to do some sort of city tour that offers sight seeing and possibly an additional activity while you on a tour group.
You'll be enjoying
world class accommodations on the Disney Cruise! The staterooms are well appointed and you've got a dedicated stateroom host to take care of you and your family. The verandah is my favorite spot to enjoy my morning coffee and even an early breakfast delivered by the already included 24-hour room service. The verandah offers a great view, since halfway it is clear and "sea" through plexiglass, and you can lean over to an open air balcony to enjoy the breeze. It's a great place to hang out while the ship enters a port. Many times, we've even watched dolphins from our private verandah swim alongside the ship. Kinda like a private escort!
I hope this helps!
