Thanks everyone for the speedy and insightful responses. Just to clarify, I'll be booking the rate under the current promo Better Tomorrows (using code ZBT if anyone's interested) so the entire stay will be charged immediately and thus I'd be entitled to all the nights, right? I'm essentially paying upfront for all the hotel bill as soon as I book it. They have to count all the nights. Should I call the hotel manager to explain the situation?
