Eric Evans of Los Angeles won a pass to the Hollywood premiere of "Music and Lyrics" with his loyalty credits from Starwood, which owns W, Westin and Sheraton hotels, USA Today reported.
He said his wife - a Hugh Grant fan - was photographed next to the star as well as others attending the glitzy film opening. He told USA Today he figured the night cost him $850.
"I said this is going to be her event," Evans said.
Other companies offering online auctions include Hyatt, InterContinental, Continental, Frontier, Delta and Midwest.
"We aren't looking for ways for members to use points on toasters or golf clubs," Starwood's Robin Korman told USA Today. Starwood's upcoming auction prizes include backstage passes to a Justin Timberlake concert and ringside seats to an Oscar de la Hoya fight.
