I bought 4 tickets on groupon (thank goodness because it was worth what we paid for, I wouldnt have ever paid more for this). I booked ahead of time and we literally made within minutes of the boat leaving. Fair warning....if you are going on a weekend I highly recommend getting to the area early. We had a 5:00 tour and left ourselves plenty of time to get there, so we thought...the traffic and parking were horrendous!!!! What we thought would be a 20 minute ride to get there really took an hour and a half because of traffic and trying to find some place to park. The boat ride was fun, we got to see a lot of beautiful homes and and parts of Clearwater we probably wouldnt see from land. There were a few dolpins but nothing like we thought we'd see, kids were disappointed but its truly not The Tropis fault. We actually saw more dolphins while walking through johns pass and it was free! Everytime the captain of the tropics boat would say a dolphin was spotted, we'd look and just see the tail...nothing exciting. And like many others have said, they DO constantly remind you to tip. All in all, it was fun but wouldnt pay for it again unless I had the groupon and was in the mood for a boat ride.
