As a Thunder Valley Rewards Member I get discounts to MGM Resorts hotels such as Bellagio, The Mirage, New York-New York, Mandalay Bay, Luxor, Aria, Park MGM, and MGM Grand, but I've never stated at any MGM Resorts hotels. Not only am I a Caesars Rewards Member but also I am a Mlife Rewards Member. In terms of benefits Thunder Valley Casino is my favorite Indian casino because they are partners with MGM Resorts. (I also was comped when I stayed at Caesars Palace for 3 free nights in July 2017 when I won their 50th Anniversary Sweepstakes.) Prior to this year there were no Caesars Entertainment casinos in California so I would go to Indian casinos. Yet I've been comped while staying at the following hotels: Bally's, Harrah's Las Vegas, and Harrah's Reno. As a member I've received numerous discounts and stayed at the following hotels: Flamingo Las Vegas, Harrah's Lake Tahoe, and Harvey's Lake Tahoe. I've been a Caesars Rewards Member (formerly Total Rewards Member) since November 2011 when I signed up for membership at Caesars Palace Las Vegas.
