Deacon Hotel is a location in Grand Theft Auto: Vice City.
The real life Beacon Hotel is supposedly one of the most haunted hotels in Miami. The reports include switching off lights, televisions screens and restroom showers. Due to these traits, the in-game hotel is also considered by myth hunters to be haunted.
A strange observation is noted that some of the lights (at night time) are switched off, while others operate. This could be Rockstar's hint towards the real life fluctuation of lights reported to occur in the Beacon Hotel.
