To go or not to go on a three day vacation that includes a timeshare presentation?

We have no interest in actually buying anything but are considering going on the trip. My main problem is that you won’t know where you’re staying until you get there. I don’t want to drive the 6 hours to make the trip and then be stuck in a dump of a place. They say you’ll stay in a three-star hotel. What are your thoughts on this? Does anyone have any experience with this kind of thing? I’d like to hear from anyone who’s done this, but I’m especially interested in hearing from you if you’ve dealt with Bluegreen Vacations Unlimited, Inc.
