it's really difficult to rent a timeshare, i'm not gonna lie, some resorts sells you nothing but lies, telling you that when you get tired of the timeshare, or when you cannot pay it anymore they will help you to rent it, but it never happens :/in my experience, i just can give you a good advice and it's trying to rent it by your own, but in case you are looking to hire someone specialized, just make sure that they're not going to scam you asking for upfront payments!
