I switched from points & points to points and miles this fall to take advantage of this "double credit" offer with Southwest.

I thought that all my stays would earn 1 WN credit this fall. Um, no. The fine print says that only CERTAIN mileage earning hotels are participating -- something I realized only after I kept receiving only a half credit.

I guess it's my own fault for not focusing on the word "participating" in the promo. I've just never had such an issue come up before in a promo of this sort. Now I know to read HHonors stuff more carefully.
