Never buy from one of these timeshare companies. Buy one off of Ebay. Prices range from $300-$600 per week. Never pay what Wyndham, etc want to sell one for. Also, beware of Wyndham as they are not selling deeded weeks. They have, what I consider, a scam going, where they sell "points". You are only buying the right to visit a Wyndham resort and paying $10-20K for that right, not mentioning all the maintenance fees.
Go out to Ebay and check closed sales, and it will give you a good idea for what you should actually pay for a time share. That being said, I've got a couple I purchased that way. It's a much cheaper way to travel. I've gone to see the Mouse in Orlando, stayed in a 4-star golf resort, 2 bedroom condominium, and my fee was $125 plus my maintenance fee for my home resort of $400. Try getting a week's hotel room with such amenities.
