I checked in for my second OTP stay at the same Marriott, Fairview Park. The same clerk checked me in. We had the same conversation....BB giving out at checkout. After about 5 minutes of talking to the "manager" in the office, she finally gave in and handed me the BB...but not before she wrote down the BB serial number.....and reminded me that the BB I just received cannot be used on the current stay.
I guess all the hotels are worry that the guest will use the BB right away. If they would take the time to read the term of using the certificate, they would know that if the guest wants to use a BB they must surrender the BB at check-in...which makes it almost impossible to use the new one. All they have to do is hands out the BB with the room key, after the check-in procedures are completed.
