GTA Online is the definitive Grand Theft Auto experience.
The customization options are the most expansive in the Casino Penthouse. Players can also order decorations for the penthouse. This is basically room service for the entire penthouse. Pick up the phone in the suite and the players will have the option to either host a party, get a car delivered via valet, order casino chips, and ask for a free bottle of champagne. The major difference in the Casino Penthouse versus other properties is the ability to access Phone Services. The player can also purchase expansions for the penthouse.
While there are different options, all this does is change the configuration of the same penthouse.
