It's not often you can identify an innovation that is an unqualified success, one that everyone would like to patent.
But for the business traveler, the all-suite hotel falls into that category. Barely five years old, the idea of offering chains of hotel rooms that are really suites, complete with their own living rooms, dining areas and kitchens - all for about the same prices as regular rooms - has become the industry's hottest trend.
Many cities for years have had individual suite hotels in scattered locations, often in renovated apartment houses. But many of those didn't offer the amenities needed to attract upscale commercial travelers, amenities such as full-service restaurants, a bar, meeting rooms or a health club. Many of their guests were travelers on a budget, staying in one city a week or more, who were trying to save money by preparing some of their own meals.
