Penn Entertainment has officially opened a second hotel tower at M Resort Spa Casino in Las Vegas. This development increases the total number of rooms and suites at the property to 765. The project was completed on budget and ahead of schedule.
The expansion includes the addition of the Montese Ballroom, a 15,000-square-foot facility that opened in October 2025. This addition brings the total indoor and outdoor conference and event space at the M Resort to over 100,000 square feet. The expansion is expected to create approximately 120 new jobs at the resort.
A grand opening ceremony for the new hotel tower is scheduled for Wednesday, December 3, at 6:00 PM PST.
