The Munro family needs a vacation. Desperately. So, Bob (Robin Williams) books a trip to a Hawaiian paradise where he, his wife, Jamie (Cheryl Hines), their 15-year-old daughter, Cassie (Joanna "Jo Jo" Levesque), and their 12-year-old son, Carl (Josh Hutcherson) can relax and bond. Bob changes the plan at the last minute, instead securing a gigantic RV for a roadtrip to Colorado. Problem is, Bob's family doesn't know he's completely altered their vacation! They're not happy when dad herds them into the RV. Things only get worse when the trip gets off on the wrong foot, Bob has trouble handling the oversized vehicle, and the Munros can't seem to avoid running into the obnoxious Gornicke family. But somehow a vacation that falls apart might just wind up bringing this family together.
