You might think about hiring a captain for your first day. Esp since you're the only experienced sailor. He can brief the crew on safety, anchoring and mooring drills and go over the cruising guide with you in depth. Let the charter company know your requirements for up to date local knowledge regarding anchoring. If you make Trellis your first stop overnight he can catch a taxi home. I think he might also be able to catch a ride back from Cooper.
