Last time LVA wrote about this was in June 08. LVA said Wynn was the only place on the strip. (Okay, you can add LV Hilton and South Point if you want to stretch the definition of "strip".)
I would seriously doubt that the Wynn still has dime lines. I'm actually quite surprised that they did in June 2008. I'm sure the Las Vegas Hilton has dime lines. The Hilton even has dime lines on NHL games, which is unheard of on the strip.
