VA1379 posted the following in the exec lounge sticky re: Tysons Corner Marriott. I've updated the lounge part in the sticky but since there was additional information provided thought I'd post it here, so that those doing a search on Tysons Corner Marriott would find it. Thanks to VA1379 for providing the info.

"there is wi-fi in the concierge lounge (and you can pick up the CL signal if your room is within 20 feet of the CL). There is one computer in the CL, one outside in the lobby, and two computers in the gift shop area. There is a printer in the CL and by the computers in the gift shop. Printing is complementary in the gift shop."

Cheers.
