also: yes it is a maze, you just gotta remember there are TWO sets of staircases, this is where most people get lost. One is more obvious and goes from the entrance down to the bar hallway. halfway down these stairs you will see a room to the right which is a balcony that looks over room 2.
rooms 1 and 2 are at either end of that bottom hallway, room three is actually halfway down this hallway to room 2, and in a sudden right turn, room three also has an upper balcony and leads to the other main staircase at the back, the other main staircase can take you up next to the smoking area which is close to the entrance but you wont be able to see it when you come in as its around a corner..... the place is a labyrinth but after 3 or 4 trips I figured it out like the back of my hand.
