During a later expansion of the hotel's pool and convention facilities, the area of the park was reduced by 40% to an area of 18.8 acres (7.6 ha). Opened in 1993 along with the rest of the complex, the then 33-acre (13.4 ha) MGM Grand Adventures Theme Park looked like a small-version of larger counterparts Disney-MGM Studios and Universal Studios, which utilized a movie studio-backlot theme. The overall Wizard of Oz theming of the hotel and casino provided the motto to literally 'follow the yellow brick road' from inside the hotel to the entrance to the theme park, which was built on the hotel's backlot. The original plan for the theme park was to make it family-oriented by providing activities for children who were too young to gamble. Opened in 1993, it closed to the public in 2000 after a history of bad performance.

MGM Grand Adventures Theme Park was a theme park adjacent to the MGM Grand hotel and casino in Las Vegas, Nevada, USA.
