The Gun Lake Casino near Wayland Michigan is getting ready expand and build a hotel and resort. The estimated $300 million project includes building a 15-story, 252-room hotel on the west side of the casino. The expansion will also feature the Aquadome, which will be three pools inside a 32,000-square-foot glass dome. The Gun Lake Casino recently celebrated the grand opening of its Phase 4 expansion, a $100 million project that included more casino floor, 500 slot machines, more than a dozen table games and three restaurants: CBK, Shkode Chophouse and 131 Sportsbar and Lounge. Project leaders are expected to share more details about the hotel and resort during Thursday’s groundbreaking event, which will start at 11 a.m. in the casino’s West parking lot on 129th Avenue just east of US-131.
