You'll receive a special award the first time you complete each of these missions, and finishing the entire story as host will unlock a much sought after vehicle for free. Perhaps more importantly though, purchasing a Master Penthouse gets you into the casino business, opening up a whole new set of missions to help the owner and staff protect your investment. As well as an opulent master bedroom with access to the Roof Terrace, complete with breathtaking views and an infinity pool, you'll be able to upgrade to install a private Spa complete with personal stylist, a Media Room to watch movies in comfort, and a Bar area that comes with a set of retro arcade machines to play on. These Penthouses above the GTA Online casino are the pinnacle of luxury, and are completely customisable to meet your partying needs.
