I took the excursion in april 2008 on the Freedom....The tour boat had a big window that was broken on departure, they had 4-5 deck hands holding a piece of plywood against the window to stop the water from getting in....they did this for almost an hour, some people did get WET. I would say that the boat held a few hundred passengers. I would guess that 70 % of the people on board got SICK, I was on the verge....my wife left some of her DNA on the boat...the waters were very very rough. The boat should not have left the dock to go to Tulum...Even boarding the boat was a problem, they had to move it from one side of dock to another side. When i reached Tulum I asked to be taken back to the Freedom, they had a boat going back near the Freedom, so we endured another rough ride back. At the pursers desk i asked for a refund of my tour price and the taxi fare... They granted it...It really was a ROUGH sea that day....
