Many reasons not to buy a TS
I was recently thinking of buying a resale TS at Marriott's Timber Lodge. It was advertised for only $6,500, the maintenance fee was about $750 a year. The owner must have paid at least $15,000 or more. But I then realized that I could rent the same unit at Timber Lodge for less than the yearly maintenance fee.
You can stay in some very nice hotels, anytime you want, for a lot less money than you will spend on a TS.
Let's us know how it works out for you. Good luck.
