Here we go again. I'll update the Hotel Resort Fee Sticky to reflect these changes. Effective Thursday, March 2nd, MGM Resorts will be increasing resort fees at all Las Vegas properties except Monte Carlo. All existing reservations will be grandfathered in with the current resort fee. Reservations booked March 2nd and on will be based on the new resort fee. UPDATE: I just got information that Vdara is not increasing their Resort Fee. See the new image.
