Unforgettable family experience! Book this tour!

Captain Sugar Bear made us feel right at home. It’s clear this crew knows what they’re doing. Captain and First Mate Alex taught us about the sea life at night in a fun and interesting way. Our first stop was at Starfish point where we got to hold beautiful red starfish and touch a jellyfish! Sugar Bear and Alex were careful to make sure we understood how these animals interact with their environment and how to safely handle them. Next we hopped over to bioluminescence bay, which was amazing! You could see the glow behind the boat as it trolled into the bay. Once stopped we all hopped in and swam. Marcella was amazing, making sure everyone got photos. 10/10 tour!

These thieves agreed to...

These thieves agreed to pick us up at our Condo which Viator CONFIRMED! They did not pick us up. Instead they stole over $300, and refused to refund. That has cost Viator our future business, and likely legal action. DO NOT USE THIS PROVIDER. Viator should cancel relationships with them.

Operator response

Hi Scott_W, We’re sorry this experience did not meet your expectations. As stated in the tour description, pick-up service is only available within the Seven Mile Beach corridor. Since your condo was outside this area, we sent you the closest meeting point and instructions beforehand. We did not receive confirmation from you, and on the day of the tour you were unfortunately marked as a no-show. For transparency, our policy notes that no-shows and late arrivals are non-refundable. We always aim to provide clear communication and a respectful service, and we kindly ask that the same courtesy is extended to our team. We truly hope to welcome you another time to experience the magic of the Bioluminescent Bay in Grand Cayman. The Caribbean Cruise Tours Team

Awesome once in a lifetime experience

Such a cool experience looked like glitter under the water. They provide suits so you don't get stung. They give you noodles to help you float because they don't want your feet touching the ground because there's little jellyfish down there. The water is shallow about 4 or 5 ft

Operator response
