Les Grandes Vacances isn't the best movie with Louis de Funès but it's a movie with Louis de Funès so per definition it's always worth a watch. He plays the usual very nervous but convincing madman, a role that suits him so good. Every movie with him is like watching a one-man-show. Remove Louis de Funès from this movie and you just have a bleak story nobody is interested in, but with the best comedian France has ever produced it's just different. I rewatched this movie just to enjoy his gimmicks and facial expressions, like most people do.
