The Americans with Disabilities Act (ADA) is requiring most public swimming pools to have a pool lift for handicapped folks. "Public" also includes private swimming pools, such as those at hotels. From a March 14, 2012 article on FirstCoastNews:
Most hotel operators told us they are concerned about drawing attention to their pools, worried their lifts or plans may not be in compliance. The ADA could slap a violator with up to a $55,000 fine. Private lawsuits could be even more.
An article on USA Today noted that at the 11th hour, the U.S. Justice Department granted the hotel industry a 60-day stay on the law due to threats of closing down swimming pools.
