The Ducum Inn is a hotel found in Vice Point in Vice City. It is a tall, curved building with a white façade, and it has a medium-sized pool with a diving board and various outdoor reclining chairs. The hotel's structure could possibly draw some inspiration from the real-life Fontainebleau Hotel in Miami, Florida.
In Grand Theft Auto: Vice City Stories, the mission Purple Haze for Gonzales can be accessed here. On that mission, he is found resting on the benches near the pool inside. The Ducum Inn may be a pun on the term "Do Cum In", which pertains to the sexual intercourse method, or a pun of the greeting "Do Come In". A Deluxo can be found to at the entrance to the Inn in GTA Vice City Stories, while in Grand Theft Auto: Vice City, there are two hidden packages in the highest diving board and in the curve behind the hotel.
