Summary is not available.

Brian and Mika Kleinschmidt bring back all their teammates to help tackle the hotel exteriors. Also, the Scott Brothers have help judging as they decide who takes home the bragging rights and the $50,000 charity prize!

Brian and Mika Kleinschmidt take on their last indoor space and it's all about luxury! With two new all-stars on each team, the luxury suites undergo a massive transformation in another epic battle!

With both hotels lacking amenities, Brian and Mika Kleinschmidt are taking the competition outdoors, and they're spending big to create much needed outdoor lounge areas. And to boot, they're bringing in guest all-star designers!

Brian and Mika Kleinschmidt bring in two new designers to help tackle one of the hotel's biggest money-makers: the kitchenette; renovations get cooking and the competition heats up as the teams are tied at one victory each.

Brian and Mika Kleinschmidt bring in new teammates to renovate the next space, which is the first and last impression of the hotel: the lobby, team Mika has no lobby and must build one from scratch, and they're looking to pull out a win.

In the extended premiere, Brian will welcome Bryan and Sarah Baeumler (Renovation Island, Battle on the Beach) while Mika will join Jonathan Knight and Kristina Crestin (Farmhouse Fixer, Farmhouse Fixer: Camp Revamp) to give new life to the standard and double guest rooms. The teams must infuse the spaces with much-needed modern features, functionality and storage, so Bryan and Sarah will employ their deep knowledge of the hospitality industry while Jonathan and Kristina will draw inspiration from their passion for older properties.
