When Kristen Bell went to exotic Bora Bora to film Couples Retreat, there was one thing she made sure to pack in abundance: snacks.

"I do travel with a lot of snacks," the actress said while promoting the new comedy, due out Oct. 9. "I was concerned about the food in Bora Bora, and so I packed a lot ... I like knowing what I'm eating. I don't like mystery dishes."

Bell says her luggage was stocked with granola bars, Power Bars, Luna Bars and especially butterscotch pudding. "I knew that all I needed was water and a mini-fridge, both of which I had in Bora Bora – in my contract," she laughed. "I made little dishes of pudding, and we had them for dessert."

Bell, 29, shared her tasty treats with costars Jason Bateman, Vince Vaughn, Jon Favreau, Kristin Davis, Malin Akerman and Faizon Love – but only they were "really nice to me," she says.

"She was like the [grocery store]," agreed Bateman. "We all would go by and ask her for little treats and stuff. She was a big hit."

Still, Bell discovered she didn't pack quite enough to make it through the five-week shoot, turning to Bateman's wife, Amanda, for one last taste from home.

"By the end, I had cleared my fridge out and I was literally bribing Amanda to give me [their daughter] Franny's Cheerios," Bell said.
