They will probably offer you $100 or an equal value of points.

Full disclosure here, we own 2 Marriott time shares (Aruba and Phuket).

If you will be there awhile and don't mind setting aside 2-2 1/2 hours of one of your days, take a look. They are VERY low pressure. We had said no to several Marriott locations before buying. They simply accepted our answer, gave us our gift and we were off.

Pick a time of day that makes sense. When in Aruba, we learned that the afternoon sun was very intense. We picked an afternoon tour so as not to be giving up too much "prime time."

I would avoid any vouchers or coupons unless they can be used in one place that you are interested in. In Aruba, they will offer some vouchers that total $100. To take full advantage, you have to go to about 8 different places and spend money.

I think the points or sometimes they offer a $100 credit towards your hotel stay are the best value.
