The two I really am not happy about:
1) the gift cheques we could get for 135,000 points! I used them on several vacations and am really PO'd they got rid of them
2) the BOGO deals were a great incentive to take a quick unplanned weekend getaway - Marriott was still making money off us considering we wouldn't have gone and stayed at all without that enticement! And they KNOW that a guest in a room is going to spend on food and drink!

Thanks for the link.
