    Okay for a few minutes
    Denise_C, Mar 2023
    This was a okay trip, I started to get a little quezy towards the end. The submarine was rocking side to side, the space was small & warm. It was hard to see, unless the diver brought the items to the windows. I was hoping it would be more clear for photographs, but that was not the case. My 10 yr old thought it was cool for about 15 minutes, then he was bored & ready to go.
    Wonderful kids activity in Maui

    Perfect for kids, divers go retrieve things to bring to the windows. The naturalist on board was so friendly and checked on me often as I get seasick. She explained everything to the many kids on board. During the ride you can go up or stay down and watch the creatures. If you’re going in the afternoon it is less likely to see turtles. My kids loved it.

    They are rude and unhelpful. The incorrect address was on the voucher and took us ten minutes out of our way. After driving the ten minutes to get to the actual location and another ten minutes finding a parking and walking to the harbor we missed the boat. I called them and Lauren was incredibly disrespectful, repeatedly stated “well the other people made it”. Also stated we would have been late any way… if we had made it to the correct address We would have been exactly 30 mins early as stated on the voucher! Offered a rebook with 20% of the amount. Why would we pay more for a mistake they made. The voucher had incorrect information on it?!? Ridiculous.
    Response from Host, Mar 2023
    Thank you Samantha for taking the time to write a review, it gives me a great opportunity to explain how tickets work: (1) When guests purchase their ticket through Viator, which is a multi international company that owns other businesses like group on and trip advisor, you are not purchasing them directly thorough us the small family owned business. (2) We never received a call from your party until after the boat had departed. It is important for everyone to know that if you use Viator for the chat or calling we don’t receive anything from them instantly, in fact it can take a day to get their communication. However, our phone number is on all guests vouchers. (3) We have reviewed your ticket from Viator and there are no differences between yours and the 1,000’s of others they have sent out. The address is not wrong, it has been our address for decades. I have attached your ticket from Viator to this review. As you can see it even has a map link you can click on to give you step by step instructions. I cannot directly comment on the other complaints and I’m happy to look into them, we do take every review seriously. Unfortunately we do not have an employee named Lauren but I will bring up your concerns to all our staff. Also you are correct we charge a fee to allow guests to come again. Large ticketing agencies like Viator don’t offer that, they want what we call a hard rule, you miss the boat you lose the money.

    It was a great experience with great guides. The divers worked hard to bring animals back to the windows so the passengers could get close up looks. Saw sea urchins and an octopus.

    Fun Experience.
    Connie_H, Mar 2023
    Great to see the reef and animals in it. Comfortable ride with AC. Loved the crew and the divers showing us a few sea animals.
    Scuba divers made the experience great.
    Bob_S, Mar 2023
    Scuba divers were great, brought creatures right to the windows. Octopus was amazing and inkd the diver.
    Wonderful experience seeing the reefs and fish from the viewpoint of the fish.
    Sandral_B, Feb 2023
    seeing the corals, the sea cucumber, talking with the guides, who patiently answered questions and happily shared their experiences with us. I would do it again in a minute.
    Donnali_F, Feb 2023
    Seeing a sea turtle on the other side of the sub. Not much happening on my side. I also liked seeing the sand star carried by the divers around the boat
    Helpful crew/guide
    Doug_L, Feb 2023
    Enthusiastic tour guide, friendly crew. Helpful in boarding and getting off reef dancer semi-submersible.
    Great short trip.
    Patrick_P, Feb 2023
    Interaction with crew. They were very good with children and knowledgeable. Location was easy to get to and it’s a nice addition to a day spent in Lahaina.

    Joseph_A, Feb 2023
    We were able to see sea turtles and an octopus. The cabin was much more spacious than I had anticipated. The whole crew from Rachel, Will, and Cylus was extremely friendly and welcoming. It was also interesting to learn that only 3 vessels similar to this one exist in the world, very very cool!! Also, having two divers swimming around made it all the much better! We would definitely recommend this activity to others that plan to travel in the area.
    Do this with your kids!
    Amber_R, Feb 2023
    This is our first time to Hawaii (my husband, two boys & myself). We loved the submarine experience! The scuba divers were a fun addition & going to the top of the boat at the end to see the views. The staff was very friendly.
    Magnificent whales! ...
    Constance_C, Feb 2023
    Magnificent whales! Fabulous staff! Watched in February 2023. Much better in a small Zodiac boat versus a crowded large boat. Would highly recommend booking everyday of your trip! No pressure to buy photos or take photos!
    Christina_M, Feb 2023
    We were able to see some turtles. The guides were very friendly and knowledgeable. It was a great experience. I would recommend in.

    Didn’t see much. Water wasn’t as clear for kids to really see creatures.. plus others got sick which was a downer
    Amazing adventures
    Bridgett_M, Feb 2023
    The divers Will, Brandon, Silis gave this tour an amazing experience. We loved their energy & interaction. And Meg was very informative. Would do this tour again when visiting Hawaii!
    So much fun.
    Jessica_B, Feb 2023
    We had so much fun. This was the perfect activity for our 4 young boys. We saw 3 sharks, 4 turtles and a bunch of other fish. They gave seashells to the kids and even gave us the picture they took for free instead of charging an arm and a leg like other places. Highly recommend this tour.

    The team was great and gave us a great tour. Megan along with Will and Angela (I think) were informative and helpful the entire tour. Thank you for a great time.
