Imagine that at The Valley Hotel you are a tourist who has just arrived and checked into a hotel. The building is magnificent, located in a picturesque valley. You immediately wanted to walk, explore the neighborhood. You quickly unpacked the suitcase, changed clothes and went to the reception to give the key. There was no one behind the counter and you decided to walk around the hotel, looking for an administrator. It is strange that in the lobby there is no one of the guests, as well as around the pool and in the corridors. And the front door is completely locked, which means you cannot go outside. This is strange and a little anxious. Find a way to open the door to avoid trouble.
