Yep, totally agreed Matt. When you factor in the time it takes to get from STT to the ferry dock, wait for the ferry, the ferry ride over, then waiting in the cattle line to clear customs, then factor in the cost of the ferry and all the fees there, the cab, tips, plus the chances of finding a zoo at STT on the way home, the cost differential between flying into EIS vs STT just doesn't seem justified to us. It is a nice, scenic flight from SJU-EIS, and on top of that, it is SO much nicer to deplane and clear customs with a half dozen other travelers, step over to the car rental counter and be off on vacation!
