@Robert1828 The caution I have regarding using Airbnb for a timeshare is the Airbnb cancellation policy. Even with a strict cancellation policy, you will only get paid for the reservation if the guest cancels within 15 days of check in. I can't speak for every time share, but many won't let you cancel your dates at all once they're booked.
Also keep in mind that if someone sends you a booking request, you have 24 hours to respond. If the timeshare property takes longer than that to respond, you either have to decline, or the dates will be blocked. Too many declines and your account will be suspended, and your placement in the rankings is dependent on accepting guests.
