I would love to tell you, but I can't. When I arrived at the hotel, I used my check-in instructions to get inside. They didn't work. I got into the court yard by running in behind a guest who had the correct code. Once inside the courtyard, we tried to unlock the box to get my key-also didn't work. I was accompanied by my 22yo son who was a student in Prague who I was visiting. Soon another guest showed up while we were on the phone with the person who worked the phones that night. While standing outside in near darkness, with all of my luggage, getting wet from the misty weather, none of us could get it to work. After nearly an hour, I'm freezing, wet and jet lagged for 14 hours of airports, flying and taxis, I'm done. We leave, go to a restaurant and I find another hotel that let me into my room.
