I wouldn't know what would be "Controversial" about asking but here is what I can offer.
The January 6th Celebration of Cudoe's Birthday is an annual event that takes place on the 6th and can spill over a day or so on either side of the 6th if it falls near a weekend. There is a gate charge to enter the town on that day and the Celebration is open to all that want to go. I personally have attended the 1999, 2001,2003,2004 and 2006 Celebrations and each has been a quality experience for me. As a backround, the town of Accompong was founded shortly after the signing of the Peace Treaty of 1738-39 with England. The town is run by a Maroon Council and an elected Colonel who adjudicates all disputes except a capital crime where the offender must be turned over to the Jamaican Authorities. Since 1739 there has only been one case of a capital crime when a man was killed over a fight involving a woman.
Finding a place to stay during this time is difficult but not impossible. Many resident rent rooms and there are a couple of guesthouses in the town proper. It is, however, not a necessity to have a place to stay as many people just stay up all night anyways. There is usually a big stage show (have seen Beenie Man, Fanton Mojah, Shaggy, Buju, etc. at different times). Also the big sound systems of Ricky Trooper and Killamanjaro play in makeshift pens around the town. Lots of good food and a friendly, relaxed atmosphere makes it unlike most venues in Jamaica.
Here is a video I particularly like that shows it best.
Respect.
