Hey there, Iris -
Welcome to the Disney Parks Moms Panel. Your little ones are going to have such a blast on the Disney Cruise. My kids were about 4 & 6 when we first visited Nassau, and I remember it like it was just yesterday. Time surely flies when you're having fun. :-)
Our family enjoyed the
Atlantis Beach Day and Discover Atlantis port adventure when my kids were little. They really loved watching the different types of fish at the exhibits, plus swimming is always a hit with my family. At this age, you'll want to bring a light umbrella stroller with you, since there is a good amount of walking to do while discovering Atlantis. You'll also be walking from the resort back to the pickup point to meet the motor coach that will bring you back to the ship. It's a good walk, and my kids were very tired from swimming at the pool most of the day. They were already asleep in their strollers by the time we started walking to the pick up point (it's a 15 minutes walk). It was hot when we were there in the summer, and we even stopped for ice cream. As a convenience, lunch is also already included with the cost of the excursion.
Our subsequent visits to Nassau were spent onboard enjoying the ship with very little crowds at the pool deck. A big chunk of guests leave the ship for the day to enjoy the port, and we've had the occasion of even having the spa all to ourselves on a port day!
Whatever you decide to do while docked in Nassau, I'm sure you'll have a great time. If you decide to explore the port, make sure you are back in time to get some rest before the evening's show and dinner. A quick afternoon nap always does the trick. And you can surprise the kids with a Mickey Bar that you can order from the complimentary room service. Helps to wake up nappers!
Happy planning,
~ Dolly
