Hi Katherine!
Thank you for bringing your question to the Disney Parks Moms Panel!
My husband and I love doing the special
Walt Disney World tours when we we visit. I think it's a great way to see some really cool "behind-the-scenes" details of my favorite place on Earth!
My family and I LOVE the
Wild Africa Trek. We did it two years ago and would like to do it again soon. The
Epcot Seas Adventure- DiveQuest is also a great choice since he is already certified. It's definitely a unique experience and one that a scuba and Disney enthusiast is sure to enjoy. It's not often that you can go on a dive where you are guaranteed to see such a variety of ocean life, and get up close and personal with sharks!
If he likes Epcot and exploring the World Showcase, he would also probably enjoy the
World Showcase: DestiNations Discovered tour. This tour allows you to see all of the amazing details that are in the eleven World Showcase country pavilions.
I hope this helps! Please let me know if you have any other questions.
