We have sailed the BVI during Christmas in July twice. If you like to party don't mind very loud Spanish music blasting all day and evening you can have a very good time with them. We found most of them to be very friendly and they are happy to include you in the party. My teenage son really liked the 'scenery'! Savanah Bay will be packed but that is red lined by most charter companies. White Bay JVD will also be packed. We didn't have any more problem getting balls in the other places than we do during other weeks we sail as most of them seem to prefer anchoring. So my advice is to adopt an if you can't beat em join em attitude and go have a great time!
