The half off deals are on rack rate. It's the norm in the hotel industry to offer half off deals - but in the very fine print it almost always says "off rack rate prices." Not a scam. Frustrating though!
I completely understand. Since it didn't say, "Internet only," or anything along that line, I thought 237 WAS the rack rate.
Have to add that I had a rough experience with our Thanksgiving trip. I got a good rate of 189 for teachers. Friend called and got 129. I called back asking about that and was told, "Well, I have a 159." I never question, but this time I did and said, "No. My friend got 129." Low and behold, all of a sudden I got 129. Just rubbed me the wrong way then, and I'm sure that is coloring my view now.
