This is the original houseboat-rental operation on Lake Powell, and houseboats here range in size from 46 to 75 feet, sleep anywhere from 8 to 12 people, and come complete with showers and a fully equipped kitchen. For deluxe on-the-water accommodations, opt for one of the 62-foot "Journey" houseboats. If you're coming in the summer, splurge on a boat with some sort of cooling system.
