Marriott International, InterContinental Hotels Group and Starwood Hotels & Resorts Worldwide are ready to compete for guests in Rio de Janeiro as the city famous for its Carnival parades and beaches races to more than double hotel capacity to host the 2016 Olympic Games.

The Brazilian city that beat out Chicago, Madrid and Tokyo must increase its hotel rooms to more than 48,000, according to an evaluation report by the International Olympic Committee. Rio currently has a capacity of about 22,000 rooms, said Gregory Rumpel, executive vice president at Jones Lang Lasalle Hotels.
