I would like to point out that many people would consider a trip to key west would be worth paying there own way. Have a nice day.
That's true. Key West is a fun place and expensive. A berth on a boat in Key West for an extended period of time might be worth paying expenses. Are you willing to entertain crew for a week or so after arrival to make their expenses worthwhile or is this essentially "get the boat there and then get off the boat?" That information would be useful.
