We did trunk bay twice, once in winter over new years and once in summer. both times went with disney group, only because we felt safer and that we wouldn't be left behind. once we did the ferry across, the other time the leyland sneed. only problem in winter was the conditions were not good and we couldnt stop at trunk bay because they are very protective of the coral reef, etc. and didn't want any churning up of the area, so ended up going to another site. Loved trunk bay though-- it is beautiful.
