As host of Travel Channel's popular series Hotel Impossible, Anthony Melchiorri is relentless when it comes to getting struggling hotels all over the world back on their feet and on the path to success. His no-nonsense approach may put some owners off, but his advice can transform even the most down-and-out properties. Yet it's ultimately up to the hotel owners to implement and maintain his changes. In season four of Hotel Impossible, Melchiorri's management skills, emotions and patience are put to the test once again. Melchiorri first evaluates each property and identifies its most significant problems. Armed with a design team to help with some much-needed renovations, Melchiorri makes critical changes that may include getting a stubborn owner with no business sense to listen or getting a lazy staff to step it up. Utilizing special experts, hidden cameras, gadgets and technology that test, evaluate and measure different aspects of the hotel, it won't always be pretty and it will never be easy, but Melchiorri pushes these owners to get it right. For many, this is their last hope.
