If you follow Walker Mangum's guidance at the BVI Pirate site, you won't have any problems. If you'd like some assistance, just follow one of the flotillas in. They typically leave Wednesdays or Saturdays from North Sound.
If you go on Saturday, make sure you go to the beach party and Jumbies show at Leverick Bay on Friday night.
