Today's glitch: I was booking a room, and selected the rate for the third tab from the left. I selected the room type, and it defaulted back to the rate that was the first tab from the left. I am glad I noticed that, as the rate I ended up with was higher than the one I wanted.

I booked via telephone and showed the telephone agent the problem -- he had the same issue. This is probably something to watch when given the choice of multiple rate types.
