Yes, I know I can go back and forth. I"ve taken the train in the "reverse" direction many times-- it's usually only airline staff on it, but it's no problem, just take the elevator down and up, as the escalators go in the opposite direction. Otherwise, I'm just looking for something fairly restful. I can't really visualize the difference betweeen a cabana and a dayroom, which seems to be the main difference between the two places?
