[3][2] Marriott's business expanded to Baltimore, Maryland, in 1934, shortly after which the company started its food services division.
During Second World War, the business expanded to include the management of food services in defense plants and government buildings, such as the U.S. Treasury.
They introduced popular items such as the "Mighty Mo", a double hamburger served in a bun, topped with sesame seeds and divided into three slices.
Similarly thick orange sherbet drinks were served in the same tall glass with a spoon and a straw, often called a "freeze".
Then in the 1950s, Hot Shoppes, Inc. started providing food services to public schools and to Children's National Medical Center in 1955, a contract which they held for 35 years.
[11] At the suggestion of the new Marriott board member Bob Wian, cowboy actor Roy Rogers was contacted to lend his name to the roast beef sandwich venture, and the Roy Rogers Family Restaurants was formed a few months later by converting RoBee's and a few Hot Shoppe locations.
This segment of their enterprise continues to be a large part of their business, providing food services to many major airlines.
Marriott had also reached an agreement to acquire Cedar Point amusement park in Ohio, but the deal was later called off.
