I went for 20 years but I am to old for it now. There is no need to buy spectator tickets. Basically they get you a few free drinks. Download the schedule and attend the events you are interested in attending. Each event day ends with a party on the beach with a band. Attendance is open. Some of the most fun is the afternoon boat parties. Ever seen 100 people on a Voyage 50!! Simply get in your dinghy around 4 PM and the parties will find you. The WillyT should not be missed the afternoon they are in the bight.
