Entry PIN and emergency phone number should be accessible online. Yes, I was given a paper slip with those details, but in a rush I forgot it in my room. Once I came back (23:30), the reception was closed and I had no one to phone so was very very close to being left outside the building as I forgot the pin. Doesn't help that emergency phone number and PIN are on the same piece of paper. Had to resort to desperate measures, and knocked on the door of the hotel in the hope that someone will hear me. I was lucky the manager of the hotel was still in the building, and he heard someone knocking so he opened. But man that was scary! Entry sistem should be revised and make it less prone to fail.
