Yeah, it is kinda odd... I have a 3 night stay coming up in Aug in Dallas that I've not decided on yet, and wondering if there is value for it there, using 2 free marriott nights and paying one extra.Took a look at the terms, it shows up as a credit to the CC you use to book. Says Amex is excluded. Also says residents of HI and NM are excluded...weird. May be useful for those minor one-off stays. Thanks Matt
