The Dayton Arms Hotel is a three-diamond hotel.
Marge and Homer were supposed to be staying at the hotel while visiting Uncle Tyrone in Dayton, Ohio. After changing their plans, Homer and Marge decided to go to Miami, Florida instead for their second honeymoon. A tornado wipes out the hotel, and Bart and Lisa are concerned for Homer and Marge after seeing the tornado on TV. When they receive a phone call from Marge that all is well, Bart and Lisa realize that Homer and Marge are not in Dayton, Ohio.
