In order to narrow down a list of countless hotels that operate in the U.S., we choose the three largest brands from each of the five biggest hotel operators: Wyndham, Marriott, Hilton, IHG, and Hyatt. From there, we consulted the American Customer Satisfaction Index (ACSI), an independent agency that scores hotel chains based on interviews with recent guests and other industry data, with a score of 100 representing the peak of customer satisfaction. Next, to factor in insights from hotel guests directly, we looked at where each brand ranked in popularity on a consumer poll of 61 hotels conducted by YouGov, as well as how many stars each chain received based on consumer reviews published on business ranking site Best Company. Finally, we gave each metric a weighted value before plugging them into our exclusive algorithm to see how each hotel chain scored on our 100-point scale Bad Stay Index, where 100 is the worst score possible.
