I emailed sixthman about what time the boat was going to start letting people on for the preparty. The only they could tell me at this time was to be at the port no later than 3:00pm the day of the preparty. I asked about alcohol. NO ALCOHOL AS CARRY ON. You are allowed to bring up to a 24 pack of water. I'm just relaying what the guy at sixthman who emailed me back said. Just a FYI.
