Worth every penny in every way - The entire experience was fantastic, starting with the price and the actual snorkel locations were both amazing. It was the highlight of our trip! Captain Russell was very proactive in providing a safe and fun experience. For example there was a speed boat that was driving through the dive area at an unsafe speed for the divers and snorkelers. As soon as Russell saw the boat he got on a microphone and got onto the driver. First hand Emily was also amazing from her engagement throughout the entire trip as well as treating me after I was stung by a jellyfish. I can not recommend sea dwellers enough if you plan on snorkeling or diving in the keys.

Great Snorkeling Trip to Molasses Reef - The crew gave plenty of assistance where it was needed. They gave more than the promised 65 minutes in the water at each stop. Very friendly and professional.

Great Times - This was our first trip taking the family snorkeling and it was an amazing experience. The entire crew was amazing, especially Emily the 1st mate. My daughter was terrified after we got to the location and Emily was so kind and took the time to help her with her fear and went to the extreme to get in the water to encourage her! It was an amazing. Thank you Emily and crew.

Snorkeling in Key Largo - At the first stop we saw rays, sea turtle, nurse sharks, and schools of bright fish. Water was rough so best to prepare the night before with Dramamine plus I wore pressure bands.

Thumbs up - Emily was very kind, helpful, and knowledgeable. We were unable to attend the day before, and they graciously moved us to the next day without any conflict.

Safe and Fun! - Can't say enough good stuff about this charter. The guys were informative, and safe but kept it light and funny. Always appreciate a good few Dad jokes! Thought I was gonna be sick and went to hide in shame, Chad found me and rather than darting the other way, offered some water. A diver came out of the water a bit destressed complaining she couldn't breath and he jumped in to assess the situation and calm her down. Homie definitely got a A++ from our crew that day. Again, great dive and experience. We'll be back.

Rushed experience - staff not vey sympathetic - as customers we felt a bit “in the way” - Too rushed the whole trip - it felt a bit like they just had to get it over with - we felt like we were just stupid and annoying tourists which kind of put a damper on the whole trip. The staff spent a looong time telling us all the thing NOT to do and it really took most of the fun out of the experience. We got really sick during the trip which was not the fault of the staff, however when someone is sick or feels uncomfortable and panicky it really is misplaced to start instructing the. to hurry up or telling the of for grabbing a bucket to throw up in (we apparently just should have stuck our heads over the railing instead, so the “poor” staff member didn’t have to be troubled with emptying a bucket of vomit. Using a bucket was apparently a no-go. Sorry to say but that is just the inconvenience that comes with arranging tours for novice tourist divers / snorklers like us. Just next time be more sympathetic- will give customers a better experience
