Mohegan Sun celebrated today the grand opening of the Earth Expo & ConventionCenter, the property’s $80 million-dollar expansion with a ribbon cutting ceremony held on Wednesday, May 30th. The state-of-the-art Earth Expo & Convention Center at Mohegan Sun is already making a name for itself as the largest exposition site along the I-95 New York-Boston corridor, with 275,000 square feet of flexible meeting and event space located next to the property’s Winter Parking Garage, adjacent to the Earth Tower guest rooms. The first major event held in Mohegan Sun’s Expo & Convention Center will be the third annual Barrett-Jackson Northeast Auction of collector cars from June 20-23, 2018.
