Disney Vacation Club is the exception. No high pressure tactics. No big incentives. I think you might get a $50 GC and a couple of fast passes. Why? Because people who want to buy DVC buy DVC. The agents don't need to give you a song and dance. Anything that needs a strong sell is something you don't want.
I'm not saying don't do the presentation. If you and your husband walk into it with your eyes open, it might be worth it. Just know it will be longer than 2 hours. However long it lasts, it will be time unpleasantly spent. Very often the initial sales person will call in a manager or some other closer. You might have to go through several of them, and you can't leave until they are 100% sure there's no chance you'll buy. I mean, you CAN leave, but if they haven't all signed off, your "free" vacation will convert to rack rate.
If you go, find out in advance which property it is. Do your homework about it. Look at listings in timeshare sales and rentals, and come prepared to show your findings. TUG (timeshare users group) is a great place to start. If you find that people are offering to sell their shares for $1, show that. Some people basically give away their timeshares just to get out of the fees. If you can book a week at the resort through an owner for less than the cost of the annual fees, show that. Point out that it would be foolish to buy something you can rent for even cheaper, with no commitment. Sales people hate it when customers come prepared with the knowledge of what the shares are really worth (hint: not much). Unless it's DVC, it's absolutely not an investment at all.
Sometimes it works to set a timer on your phone, and state you'll give them the 2 hours, but it might not, if the salespeople are really aggressive. Also, if there's a meal offer there, realize the 2 hours probably doesn't "start" until after the meal.
Just make sure the time you're going to invest is worth it. For me, I don't get enough vacation to spend half a day of it in sales purgatory. But if you have the time, and it's a free vacation with half a day of high-pressure sales tactics vs no vacation, then it might be worth sacrificing the time to do it.
