Coca-Cola is becoming Marriott International's official beverage partner.

Marriott guests will start seeing Coca-Cola's brands across guestrooms, restaurants, lounges and events via a phased rollout starting Wednesday and continuing over the next several months.

The move is an effort to better meet guest preferences, Marriott Chief Executive Anthony Capuano said.

"We are focused on delivering the products our guests and Marriott Bonvoy Members know and love, better meeting guest preferences, and creating economic benefits for owners and franchise operators across our system," Capuano said.
