"They were canoodling around 1:30 a.m.," the eyewitness tells Life & Style. "They were holed up in a corner on the first floor."This isn't the first time Ryan, 30, has fallen for an older co-star. Before meeting the 37-year-old Eva on the set of their new flick The Place Beyond the Pines, Ryan mixed business and pleasure with Sandra Bullock, 47, while filming Murder by Numbers in 2002. And just two years later, he revved up a long-term romance with Rachel McAdams, 32, his co-star in The Notebook.

And Disneyland seems to be Ryan's go-to place for a first date. Before taking Eva there over Labor Day weekend, he took Gossip Girl star Blake Lively. He also took actress Kat Dennings to the California landmark in 2009. "Disney is just a really incredible place," he's said.
Ryan insists his career comes before love ("I'm currently too focused on my career to date anyone. I'm in a committed relationship with film; I'm giving as much to it as a marriage," he says), but it seems like he may be making an exception for Eva. "They were obviously together," adds the eyewitness. "They looked really into each other."
