My associate and I stayed out until 3AM and were looking forward to crashing, but out of the blue my door card didn't work. A minor inconvenience, except that there was no one at the desk. I beat on the bell, shout "hello?" several times, and then I notice a sign saying we're cleaning rooms and to call this number to let us know you're waiting. I called it 8 times, listening to it ring approximately 4 feet from me - no answer. Fortunately my associate was noticed sitting in the hallway, waiting for me to come back with a working key by a cleaning lady. With total disregard for security protocol, see unlocked the door for him. I was called and told to come on up. Turns out that the cleaning lady was the manager. The manager was cleaning rooms at 3AM, leaving the desk completely unattended. Why do you have your managers cleaning rooms - and at 3AM no less? Why do you not keep the front desk staffed? It is infuriating for your key to not work and you have to spend 30 minutes wasting your time to get it unlocked. I was so spun up that I could not get my required 4 hours of sleep before checking out. In turn, I booked another night as I was too tired to drive.
