We are doing that on the way back this year. Saving hundreds by staying a few extra days. We are going to hang out with long time So. Cal Hobie sailor Teri Mckenna in St Thomas. She owns a charter cat "Safari" (Safari / Lagoon 440) and hopefully she will be picking us up at the Bitter End if she doesn't have a charter that week. Otherwise we will be taking the ferry.
