My comments are made on the basis that one is buying a timeshare for mainly trading purposes. All of the statements I will make are actual experiences not something someone said, or I heard somewhere. My family has been involved in timesharing since 1980. First my parents then my sisters and myself, now many of my extended family members own timeshare weeks. I am average income (work everyday), average intelligence. So since I did it anyone with patience, a minimum amount of time, and dedication can achieve the same results.
Before even considering purchasing a timeshare, please talk to people who have had bad experiences first. This way you will be leery of everything going on. Better yet just follow my advice and have no problems at all (just kidding).
After deciding to purchase, remember no matter what resale is better. My reasoning for this is, there are a lot of dissatisfied owners out there willing to take a loss just to get out. So make their mistake your marvel. I have been and continue to take tours while on vacation just to stay intuned with the pricing of weeks. I have yet to find a resort that comes close to fitting into my price range of $2500.00...
