I am one of the Paradise Villas owners and I have never heard about this. All the villas are individually owned, though, and I only advertise and book my own two units and don't offer any other travel products. I book mine exclusively via my home page.
One of the owners, Bill Toonen, is a travel agent and he may be bundling some kind of special deal in with his personal condos. He owns several units. His business is "Tradewinds." If its not him, I would be a bit leery because I don't know of any other owners who are travel agents and who would have the airline connections to make that kind of offer. Usually when something sounds too good to be true, it is...I certainly could not make such an offer for people who book my two units even if I had time to get involved in travel agent stuff, which I don't....
