Hotel Hell Vacation is an American online comedy short film released on February 7, 2010 on HomeAway's website. Chevy Chase and Beverly D'Angelo reprise their roles as Clark and Ellen Griswold. It was the first time Clark and Ellen had been seen in a Vacation film since 1997's Vegas Vacation; they later appeared together again in 2015's Vacation. The fourteen-minute short premiered as a series of commercials during the Super Bowl to help promote HomeAway, Inc. Although sanctioned by Warner Bros. (which holds the underlying rights to the Vacation series characters and concepts), this film was not sponsored by National Lampoon, Inc., which initiated the Vacation series.
