As the economy slows more and more people are affected and maintenence fees are payable for your lifetime or until you sell. I enjoy the sales person who says, but your points keep comming back every year without mentioning your cold hard cash is what makes these points come back each year.
Timeshares are a luxury, and people cannot afford to vacation as much. If your home equity line is maxed out, credit cards are maxed out, you will have to unload somethings to make ends meet. WYN, sales are slowing and the increase in retail prices will slowly fade and start going backwards. This only makes sense because land is cheaper and buildings are cheaper today when compared to last year.
Oceanfront properties cost more to maintain and are at higher risk, thus higher maintenance fees. Vegas is slowing and the resort requires 300K to really have fun, so people are selling what is really an average size package for Vegas.
