Henderson, Nevada, United States · Independent · Accessible Luxury
The Marnell family opened M Resort on 1 March 2009, a billion-dollar house at the south end of Las Vegas Boulevard in Henderson. PENN Entertainment bought it in 2011, and a second tower in late 2025 brought the keys to 765. AAA has named it Four Diamond for 2025, a spa-and-casino campus that is still the Marnells' bet on the far south end of the boulevard.
