Re: sailing BVIs in February for a week
Trellis Bay has a nice "artsy" area and a nice resteraunt. See if the full moon is the week you are there, since they have a nice full moon party.
Bitter End on the north end of Virgin Gorda, is a nice place to spend a day or two.
Indians are great snorkling, and you can go from there over to The Bight on Norman Island, for the night.
Don't miss a day at the Baths on the southern part of Virgin Gorda, and then you can spend the night on a ball, off of Spanish Town.
Good Snorkeling off of Monkey Point, at the southeast of Guana island.
Most of these give you the quiet side of the BVI, without the late night stuff. But you are close to it, if you decide to jump in.
