Maybe more like big brother or jersey shore?XD why are we keeping a barrier up? Alright I would say keep them on a island that way we get both the freedom of movement while keeping them "trapped" It would be interesting if each one was offered to come to the island in a specific way that would appeal to the human character. cause lets face it this many different personality types wont do it for a dating show.
Though I do agree that it can all be revealed at once they have been tricked xD
