Since we had a small child with us, we decided to go with this plan that included a glass boat where we could look into the ocean with our clothes on. My child was so excited to see the fish that I was glad I brought him along. The staff took good care of the children during the snorkeling afterwards, so the parents could enjoy the tour without worries. I really appreciate this tour for families.

I was traveling alone, but the staff spoke to me in a friendly manner and I was able to enjoy myself without hesitation. I spent a relaxing time on the glass boat and was able to immerse myself in the beautiful marine world during snorkeling. I think this is a good tour that allows one person to spend a fulfilling time without floating.

Good facilities. The view from the boat was beautiful. Easy and efficient transportation. The only regret was that we had to wait for the weather for a little while.
