Marianneg,your plan is perfect, stay at Captain Oliver's the night before,take a taxi to Grand Marche next day and provision for the bulk of the trip. The night you stay at Capt. Oliver's have dinner at the Dinghy Dock Bar. A few ideas,if you are sailing to St.Barts, a nice overnight is Ile d' Forchue. Nice evening anchorage. If you are headed to Anguilla, on the way there or back a night in Grand Case is great, and I agree that if you can make it a Tuesday for Harmony night that is a bonus.
