We used to book rooms for the job fairs but don’t now as they aren’t that good of deals. I’d recommend whatever hotel chain you patronize or AirBnB. Specific advice under each city based on location.
DC – August – Arlington VA
The job fair is always near Reagan Airport and the networking function is always close to the Penn Quarter across the river in Washington DC. SO I always recommend staying somewhere near the Blue or Yellow lines of the metro. You can stay near the yellow/blue line in Arlington OR in DC and you won’t need to cab or Uber if you don’t want to.
Bremerton/Bangor/Seattle – November – Bainbridge, WA
This career fair in Bainbridge is at the art museum 100 yards off the Bainbridge ferry terminal with the networking event in Seattle a half mile walk from where the ferry lands. So you could stay in Seattle or Bainbridge convenient to the ferry.
Pearl Harbor – January Pearl Harbor/Hickam
We used to do the events in Waikiki but it was too far for the nukes. All future events will be convenient to the Pearl Harbor base.
