BTW, Tahiti Village is associated with both Interval and RCI. So you could either timeshare company - - or both. Both have units that can be rented by the week. Interval calls them getaways. RCI calls them "Last minute vacations (?)"
In either company, You don't deposit or lose your week - - you're just renting a timeshare. Typically the rental cost is much less than the maintenance fee you'd pay if you owned the timeshare. So, it's a bargain. RCI has more resorts and lists lots of WorldMark and Wyndham timeshares and HGVC (Hilton). Interval has somewhat fewer timeshares but has the cream of the crop: Marriott, Westin, Hyatt, Disney, Sheraton.
I've stayed a T.V. twice and enjoyed my stays both times.
If you bought Tahiti Village from the developer, you probably paid several thousands of dollars. If you bought it on ebay, you probably paid a couple hundred bucks or less. So, if you are still in the rescission period check ebay using the key words Tahiti Village timeshare and do an advanced search on completed listings. You'll see a bunch under $100. If you are beyond the rescission period, just ignore the last paragraph and enjoy your new timeshare.
