I know NOTHING about the resort, or your "vacation Club". BUT, right now, selling a timeshare, especially a RTU, is almost impossible ---at least for any "real" $$$. Maybe you could get rid if it for under $100. (You might have to PAY someone to take what you own !!!)
As far as renting --- do you mean that you want to rent your time to someone else? That might be possible, BUT, where will you find a renter? There are "many" companies that want YOU to pay "big bucks" to them, for their "guarantee" of renting it. SCAM !!! DO NOT pay a company an upfront fee to rent your unit. You will be just losing your $$$.
