Welcome aboard, Becky! I'm so excited for you to experience a Disney cruise to the Bahamas! I just returned from another four magical nights with Disney Cruise Line in the Bahamas and always enjoy the fun Port Adventures Nassau has to offer.
Atlantis is quite a spectacular resort, so I'm glad you'll get to experience it. If you or your husband plans on joining your six-year old for the dolphin interaction and the other adult plans to take your littlest one on the
Dolphin Cay Observer adventure, that's perfect! One adult must be in the water with your six year old, but the other one is free to pay the reduced cost and simply tag along to observe and take care of the baby. You'll see that the infant price is $0 for the Observer adventure. Since your little one is free, the reservation system will not allow you to add him or her when you book this adventure. Don't worry! You simply arrive at your adventure meet-up spot with your whole family, baby included, and you'll be all set! Plan to bring an umbrella stroller for this adventure, as it will be quick and easy to fold and stow!
Have a wonderful time as you continue to choose your adventures and plan your cruise Becky!
