Mystic Lake is fast approaching the Jan. 1 deadline for its latest expansion, which will transform the Prior Lake entertainment complex into one of the Twin Cities' largest hotels — just in time for Minneapolis to host Super Bowl LII.
The ambitious $90 million-plus project will attach a nine-story, 180-room hotel and event center to the existing 586-room Mystic Lake Casino Hotel, adding two ballrooms and a massive glass atrium with scenic views of the golf course.
Treasure Island Resort & Casino near Red Wing also plans to open an expansion by the end of the year that will have 21 more rooms than Mystic Lake. The biggest hotel in the state is the 821-room Hilton Minneapolis.
The Shakopee Mdewakanton Sioux Community (SMSC), which owns and operates Mystic Lake and nearby Little Six Casino, said growing demand was the catalyst for the expansion. It's on track for an early January opening and already is fully booked for the Feb. 4 Super Bowl at U.S. Bank Stadium.
"There is no wiggle room," said Tom Polusny, Mystic Lake Casino Hotel's executive VP of operations. "The only thing that would prevent it being done on time is an act of God."
The addition, dubbed Mystic Lake Center, will include a 70,000-square-foot event center with several breakout meeting rooms and executive spaces to help attract lucrative convention business.
Officials say the sheer size of the expansion will result in a more diverse clientele, opening the door for large-scale events like concerts, weddings and theatrical productions. A huge industrial kitchen behind the ballrooms can serve up to 3,000 people. Previously, Mystic Lake was mostly limited to crowds under 500.
On Thursday, construction crews fitted insulation in interior walls.
