The bubble boy has a new place to stay in Las Vegas: MGM opens 'Stay Well' rooms

As part of a major renovation, the 5,044-room MGM Grand Hotel & Casino in Las Vegas is launching 41 "Stay Well" rooms and suites next month that contain features it says will improve sleep, reduce allergens and promote healthy eating. The rooms, which will cost about $30 more per night than a typical room, are the result of a partnership with Delos LLC, a New York real-estate development company that aims to infuse architecture with health-promoting technology.

Delos worked with an advisory board of eight doctors and researchers from Columbia University Medical Center in New York to plan the Stay Well rooms. (The Cleveland Clinic is also a partner.)
