MGM Resorts International owns both MGM Grand and Park MGM.
MGM Grand is the place to be for the very rush life Las Vegas is known for. With its nature-themed look, the Park MGM provides its guests with a calming and soothing vacation/business destination where they can relax. The main difference that separates the Park MGM from the MGM Grand is that Park MGM is for a quiet experience while MGM Grand is for the extravagant Las Vegas experience.
