Sounds like you'll be paying 1.5x liveaboard prices...
I will happily room with anyone who offers to cover half of my cost to come on the trip and will sign a binding contract wherein I will promise not to snore at all.
Hell, as I think about it, if anyone wants to pay 1/2 my cost to come on a liveaboard trip with them I will promise to sleep in the salon, use the deck head, and shower on the back of the boat! You'll never even know I'm on board...
