Hi Peggy!
Welcome to the Disney Parks Moms Panel! I am thrilled to hEAR you are heading to the Bahamas with Captain Mickey aboard the beautiful Disney Dream!
On my family’s most recent sailing, my boys were finally both old enough to participate in a dolphin interactive excursion and let me tell you – it may have been the highlight of their lives! I guarantee that those in your travel party will have an incredible experience as well!
Based on the age range of your group, it does limit you to the
Blue Lagoon Island Dolphin Encounter (N21), the
Atlantis Shallow Water Interaction with Aquaventure (N27) or an afternoon Discovering Atlantis (N47). Both of these are great options and I feel that your dolphin experience would be very similar although according to the details, it appears that the Atlantis experience may give you a little longer actually with the dolphins. With the ages participating and your comment that all are swimmers, I would narrow it down to either the Blue Lagoon OR the Aquaventure. Blue Lagoon is a beach where you can opt to spend more time there if you have a morning departure time or the Aquaventure is a waterpark with slides, pools and even beaches to lounge at. Be aware that there may be a minimum height requirement for some of the waterslides that you want to take into consideration.
I really do not think you will go wrong with any of the dolphin encounters and can guarantee that it will be an experience that everyone will remember for a long time! Because they are popular excursions, I recommend booking early to ensure availability.
Happy Sailing!
