Today we won a "trip" to take to Orlando for 5 days and 4 nights, along with 2 passes to Disney World. It's with www.bluegreenonline.com which is a timeshare company, and it means we need to sit in on a sales meeting; which is fine if it means free hotel stay! We've always been interested in owning timeshare; but know nothing about them. So what can you tell me about them? what is the average start up cost, monthly fee etc?
