Awesome underwater experience - Awesome experience would definitely do it again! The crew and divers were awesome and looked after everyone at all times. Plus, you were able to snorkel while the other group was going, which was great as well.

You Must Try This - The staff was very careful with our safety the entire time. It was a new experience for me but they were all reassuring. Being under water like that was definitely scary for me lol. But I’d do it again

Disappointing outcome, but nice staff - This tour will definitely cancel on you last minute. I booked on Friday for a Sunday excursion. They notified us Saturday evening (late) asking us if we could possibly reschedule, but provided no reason. I responded to the message that we couldn’t reschedule since we were flying out that same day and asked if we should still show. They never responded, so we showed up at 8am that Sunday as stated in the instructions. The tour guide was there, and he was very nice, but he just told us they weren't doing the tour that day and to request a refund. In my opinion, if they weren’t going to run the tour on Sunday, that day should not have been offered to schedule. Very disappointing, because it was my most anticipated activity on the trip.

Very Unprofessional - Very unprofessional. We waited for an hour to do the excursion to find out it was canceled. We didn't receive anything saying the excursion was canceled. We contacted Viator to get a refund and now we are waiting for the excursion to contact Viator to confirm it was canceled.

Poor “day of” communication when they cancelled the excursion - Cancelled on us in person and told us to get a refund by cancelling through Viator, but it is not set up to process weather-related refunds.
