Throughout the presidential campaign, Romney made a point of staying at hotels operated by the chain throughout the country, even when other options were more convenient. The Romneys and Marriotts are both prominent families within the Mormon Church.

Romney's return to the board was heralded by top executives at the hotel chain.

"Gov. Romney has proven to be an astute, independent director who is fluent in the demands and opportunities of our highly competitive industry," said Marriott CEO Arne Sorenson in a statement. "We are fortunate to have him back on our board."

Romney's previous tenure on the board of Marriott actually became a contentious point early in the campaign, when President Obama's campaign was pressuring Romney over moves Bain Capital had made in 2001. The Romney campaign argued Romney had fully resigned from the firm in 1999, but Democrats pointed to Romney's continued service on the Marriott board — a Bain client — to argue he remained active in the company.
