A year after the motel opened, a group of investors doubled its size by adding 40 rooms and a conference center with a seating capacity of 250. It wasn’t long before the Biltmore began to attract company meetings and little conventions. In 1964 a little fire caused structural damage to a number of rooms, but they were quickly rebuilt and remodeled.
In the 1970s, the motel’s restaurant became a soda fountain, decorated in the style of the Al’s Diner on the Happy Days TV show and a women’s boutique called Lucille’s were added to the amenities. In 1984 the mid-century modern Biltmore also known as “Edina’s Guest Bedroom” was demolished to make way for new condominiums.
