I like Gift Cheques. I get the best deal I can at the hotel, then redeem whatever batch of $1,000 worth I need (or can get) for 135K points. I used those to pay for anything I can charge to the room. In return I get MR nights credits and I earn points on the room charges. I've done things like stayed at an airport Marriott and used the park and fly promotion and paid with cheques. So I get a free room, perks and free parking for a week. I've charged theme park tickets, drinks, food, souvenirs, massages (for the wife), parking, dinner at Ruth's Chris (some Marriott's have them) and so forth. I refer to it as my Marriott play money.

Last year I redeemed $4,000 worth of gift cheques for 540,000 points. The only downside is they're only good for one year from issue date. But they never sit around my house that long.
