I was just looking to book a room in April in Bangkok. I thought I'd consider the Courtyard as this will be a shorter than normal stay, I've never stayed at this one, and it's really close to good shopping.
So I look on line. I see the Deluxe Room (cheapest one they have) for 2,700THB per night. Then I see a tab for "Marriott Rewards Offers". Cool, I get a discount for being an MR member. Rate for exactly the same room? 2,820 THB. 120 baht more per night. What a great deal.
Even better, if I go with the Grand Deluxe Room as an MR member I get it for only 3,120THB per night while the lowly nobody off the street gets it for 2,970THB. 150 THB less.
Am I missing something?
