From National Lampoon’s “Vacation”, the last motel they stayed at, with the infamous skinny-dipping scene. I randomly found myself staying at this hotel on New Year’s Eve a couple years ago, and boy, they are NOT shy about letting you know this scene was filmed here! The lobby is full of posters and photos from the movie. The piano bar is still there! (although it was closed during my stay). (Hotel Saddleback, 12500 Firestone Blvd, Norwalk, CA)
