I've owned a few timeshares throughout the years and have purchased both new and used timeshares. I'd recommend going with used. You get the same exact property for a fraction of the cost and usually are given more options.

Plus you don't have to deal with the pushy salespeople. (They know they've got a limited time to sell you, so they're all over you to commit.) With sites like this one, you can shop at your own leisure. Hope this was helpful.
