The company unveiled its first Go There Virtual Meetings studios at the New York Marriott East Side Hotel and Bethesda North Marriott Hotel and Conference Center near Washington, DC yesterday.
The openings are part of Marriott's plans to roll out the technology, which enables groups to meet in multiple locations worldwide in real time, across 25 hotels within the first six months of 2010.
The AT&T and Cisco Telepresence technology service combines high-definition video, real-time audio and interior design to groups feel as if they are gathered in the same room across a virtual table.
Executive vice president (eastern region) David Marriott said the system would "give us the opportunity to tap into a new revenue stream" rather than cannibalise existing business.
He said: "Think about the webinars that might have been occurring in offices up the street - we're bringing those people into our hotels."
Grosvenor House general manager Anthony Stewart-Moore said the six-delegate suite would be a "fantastic add-on" to the hotel's events offer, which would work in combination with physical meetings.
He said: "I think we'll get more use out of our meeting space. The hotel is in the heart of Mayfair so I could see a lot of use late at night between diplomats."
