Buy Marriott Timeshare Resales

Thinking of buying a Marriott timeshare. Is it really the resale of approximately 1% of the original purchase price?
The company has units of participation in the individual for $ 2,800. Marriott will sell for $ 35,000. If you don "t buy directly from Marriott, you still is entitled to all benefits?
First, the calculation is not too good. 1% of $ 35,000 is $ 350. 2800/35000 is 8%. Timeshares can reduce and often have higher maintenance costs. Many people regret buying. If (and this is a great high SI) examination, the resale market would be (much, much more cheap). Good luck!
