5.00We chartered a private boat with Captain Alex and skipper Megan. The experience from start to finish was incredible! We felt well taken care and safe the entire time. They customized the experience to us which was so special. They always made sure we had what we needed and were comfortable with drinks, etc. Megan snorkeled with us and helped us find the good spots. Captain Alex also acted as our DJ playing great music on the way and telling memorable stories. He was incredibly knowledgeable about all things St Thomas and the sea. We even contacted them to see if they could take us on another boat trip before we left because they were so wonderful. If you charter a boat with Seas the Day, make sure you request their team. They are the best! All the sights were amazing but the two of them really took it to another level. Thanks Alex and Megan!!!
Ok, but not the experience we had last time. We won't be back.

2.00We had a group of 8 that did a half day afternoon charter on one of their catamarans. This was our 2nd time doing this excursion with Seas the Day, we returned because it was such a fantastic experience the first time 2 years ago. Unfortunately this time was nowhere near the same experience. It started off with someone getting upset at part of my party for using a restroom that one of the crew took us to use. When we arrived at the snorkeling locations we parked a long distance from the area they suggested we swim to. Also, the crew didn't seem to give very good guidance on where to snorkel. The 2 areas we snorkeled were not good at all. Almost no rock or coral formations, almost no fish and we didn't see any turtles or rays. While I know they can't control the marine life in the water, it seemed like more of a location issue compared to our last experience with them. Finally when we got back a little late, then the crew couldn't open the gate at the end of the dock. Thank god I was in contact with my driver and he waited for us as it was getting tight to get back to our Ship. Someone on the other side finally came over to unlock the gate. We got back to the ship about 20 minutes before departure after a 'fast' drive back by our driver to make it before our ship departed. I will say, the crews were friendly enough and it wasn't a 'terrible' experience but was nothing like what we had 2 years ago. Overall an ok experience on the boat and a poor experience snorkeling. The last time our glasses were always full with rum punch, that was not the case this time. We won't be booking again in the future.

5.00We took our "tribe" out on Seas the Day for a full day trip of laughter, outstandingly beautiful scenery, and immense wildlife. Capts Alex, Rogan, and Philip planned an exquisite journey with three snorkeling sites where we saw a shark, sea turtles, and thousands of brightly colored fish and sea life. They gave us details of the history in the islands we were visiting, and even pointed out Taylor Swift's favorite place to stay when she visits!! Maho Bay and Trunk Bay have the most incredibly beautiful water I've ever seen. 10 out of 10 starfish rating for this adventure. It was the highlight of our trip!! Highly recommend!!
Amazing

5.00Capt Wallens & Ro were great guides to snorkel on St Thomas & St John. Our first stop they parked literally in the middle of coral reefs filled with tropical fish. It was like swimming in a tropical fish tank. Next stop was Maho Bay where we were only one of two boats so no crowds at all. Lots of sea turtles and calm water. We headed back to Red Hook watching a beautiful, stormy sunset. Perfect day for our sibling trip!
