The property's A-lister days appear to have passed, but Green Valley is still an impressive, full-service resort. In 2004, the Discovery Channel used the resort as the setting of a reality TV series, 'American Casino.' Today, however, it mostly attracts more couples and conference attendees - and a steady stream of locals - than celebrities. When the Green Valley Ranch first opened in 2001, it was a see-and-be-seen scene, with Bill Clinton lounging by the pool and George Clooney hanging out at the bar.
