This was an amazing activity. We all had so much fun. The tour guides were very professional but fun. My husband even had a small octopus stuck to his helmet on the up to surface. Highly recommended. (Marti Haug-Smith)

This was really fun, the divers and crew are really professional. A few people lost phones, and a ring. They went above and beyond to find them for customers. These men earn their tips, so I tipped them.

a bit noisy but great fun

20 or so guests are taken out on a boat to where the submarine scooters where you are free to snorkel while you wait for your turn on the scooter. They run about 4-5 at once, each with a guide - probably spending about 20mins under the water. Execution seemed to be well coordinated, everyone had fun. Only negative is the loud high pitch noise you will hear while your head is in the “bubble” of the scooter, but you will forget is quickly once fishes surround you.
Excellent for those with physical disabilities.

The crew was extremely accommodating. Both our kids have muscular dystrophy and one of them has very little muscle control. The crew worked with us to get the boys onboard safely, into and out of the water and made sure they felt safe and secure the entire time. Can’t express our gratitude enough.
Outstanding memories, a true highlight of my vacation

Like everyone else has posted, it truly is a memorable, once in a lifetime experience. The price is excellent, every member of the crew is friendly and professional, and every effort was made to make sure our time out on the ocean was first rate. Just one recommendation if you take this adventure; don’t forget to tip the crew. You’ll see, they deserve it!
Once in a Lifetime Adventure

I am a non swimmer scared to death of the water, but the diver they assigned me was so great at calming my nerves and making me laugh. Best experience I have ever had. My wife had an octopus on her hand and couldn't stop ewwing and awwing and smiling. If you ever do anything out of your comfort zone do this. Simply amazing.
Awesome underwear adventure

Going underwater in the sub scooter. Being able to swim while waiting for my turn. The pictures that were taken by the crew were awesome!
