Travelers trying to power up on Vitamin C may find fewer options at breakfast buffets. Executives at Marriott International said the hotelier may drop items such as some fruit selections from the breakfast buffets -- or ditch them entirely for menu ordering -- if occupancy rates at some locations are too low because fewer people are traveling.

"You need to provide a breakfast experience, but you don't necessarily have to provide a huge spread to do that," Laura Paugh, the Bethesda, Md.-based company's vice president of investor relations, told analysts recently. "So there's always more things you can do should business continue to weaken."
