'Over the years, we’ve all heard or maybe even said it ourselves: When is Gun Lake going to build a hotel?' said Gun Lake Tribe Chairman Bob Peters. Just to the west of the casino, construction begun on phase five, which will include a 15-story, 252-room hotel and 32,000-square-foot aquadome. That phase included three new restaurants and an expanded gaming floor space. It is their latest phase of construction, wrapping up their last phase only eight months ago. Gun Lake Casino broke ground on a new hotel and resort on Thursday.
