CascadiaCon is spread out between two facilities: the Seattle Hilton & Conference Center (itself spread out between multiple buildings) and the Radisson Hotel down the street. Some of the panels I was scheduled for today and that I wanted to see were down in the Radisson. On the way back, I did a Standlee Unit Measurement -- that is, I counted how many of my paces (which are approximately 1 meter/1 yard/3 feet) it is between the front door of the Radisson and the front door of the Hilton.
I can report that the Radisson and the Hilton are 745 Standlees apart. This is a fairly good hike. I reckon it's a good thing, though, as otherwise I wouldn't get my regular exercise during this weekend.
There is, by the way, a continuous shuttle bus service between the hotels.
