Other than Trip Advisor, PaCommEx attendees can search Trivago.com or Hotels.com . At Hotels.com you can specify the area near the Living Computers: Museum + Labs, our venue for PaCommEx.
The more inexpensive hotels are located near the Seattle-Tacoma International Airport, about 8 to 10 miles south of the LCM+L. In your search, you can specify “SeaTac” or “Seattle-Tacoma International Airport”.
