This excursion was thoroughly enjoyable in all aspects. Viator was very professional throughout the entire process with the email communication, the directions to their location and the efficiency of the actual tour office on the island. The semi sub was amazing in that the tour guide was extremely knowledgeable and that the reef was incredibly beautiful. You actually felt that you were scuba diving, but you were very comfortably inside. Feeding the fish was amazing. The diver made sure that he came to each window so that all could get a good view. Very enjoyable experience from start to finish!

Our entire family (including five kiddos ages 1-11, my husband and I plus my parents) just loved this excursion! We had a fabulous time; it was one of the highlights of our vacation. None of us felt even slightly nauseated, and we all had awesome views. The guide was knowledgeable and friendly.

Great to see all the fish and ship wrecks. They were so helpful to my husband since he just had back surgery 6 weeks ago

The guide was very informative and explained everything in detail and was funny. The "submarine" was clean comfortable and our trip was shared with only one other couple that day. We stumbled upon this trip by accident on line and im so glad we did. Had a blast.

We really enjoyed the Simisub tour. I think that may have boosted our courage enough to take a real submarine tour next time! Thanks for adding a highlight to our cruise.

Great excursion. Guide was very informative, engaging and helpful. All of the family enjoyed it and we saw saw some wonderful fish and other incredible sights especially the fish feeding. Would definitely recommend as a fun, exciting and educational experience and much better than a similar event we experienced in Cabo San Lucas a few years ago.

The tour was fine the directions were not. The referenced point "Hard Rock Cafe" is closed so you need to update directions to the Atlantis which is shown on local maps and nothing about Grand Cayman Shore Excursions is known by the locals nor has signs to identify. Two locals sent us in opposite direction.
