SocInfo 2016 will take place in Bellevue, WA. Bellevue is just across the lake from Seattle, WA, and is a lively city in its own right. There is a direct bus from the Seattle Airport to the Bellevue Transit Center via SoundTransit (http://www.soundtransit.org/), which should take approx 45 minutes. Alternatively, a taxi ride would take 25-30 minutes and costs ~$50.
The conference will be held in Meydenbauer Center, on the 4th floor. Below you can find the map of downtown Bellevue. Green star shows the venue’s location.
