I purchased a Groupon Special online. It was easy to make a reservation.The Sightseeing Cruise is located at Tin City. Checking in and boarding on the boat was easy.There weren't alot of people for the 4pm curise, Memorial day weekend. There were alot of available seats upstairs and downstairs.The Sightseeing Cruise is about 1.5 hours. As we set out on the Bay,we saw alot of multimillion dollar yatchs,and homes. It was very interesting hearing about who owned the homes,cost and how long the million dollar homes were around. I finally saw what I was waiting for, Dolphins swimming alongside the boat. My daughter and I were in awe. We were able to see mangroves, birds, more Dolphins and a manatee. We also went out into the Gulf of Mexico. The crew were very welcoming and knowledgeable.This Sightseeing Cruise is highly recommended. Everyone should experience this Sightseeing Cruise.
