Thank you so much for the round-trip transportation! The ladies who greeted us were so warm and lovely, and the snorkeling instructor was incredibly dedicated, always trying to take beautiful photos for us! Highly recommended, even non-swimmers can participate!! (Attached is a picture of the sea turtles we saw!)
Highly recommended! The tour guide was very attentive. Although the weather was very hot, everyone had a great time.
