The Harris family, Mom, Dad, Olivia and Nathan invite Grandma Pat on their fun trips a National Park every year. Grandma loves spending time with the family and always says yes to fun and adventure. This year Yellowstone National Park is their destination. However, according to Nathan, Olivia can't keep her eyes open and misses many of the fun sights and sounds of the park. Will Olivia wake up and realize there is more to enjoy on a vacation than napping?
