the newest "trick" with time share presentations for free play or comps is this:

Now they ask you to give them an actual cash deposit and if you don't show up for the session that you paid for you lose your deposit. I ran into three different "offers" like this over New Year's Weekend.

I don't know what the Westgate time share deal is, but it wouldn't surprise me if they have a similar plan now. What one does, others copy.

Regarding the presentations: generally two hours with or without breakfast (whatever that is).
