Rose Quarter - Convention Center
Not sure if you need to be on easy public transport, but the venue is right on the MAX Green line and 3 blocks off the MAX Red and Blue lines. Parking is challenging around the venue itself (although there is a Smart Park nearby).
I’d look around the Oregon Convention Center area, which is on the Red and Blue and Green lines. I’m having trouble remembering the one that was just remodeled, but there are ~20 hotels around that area.
(Plus side: Wordstock is at the Convention Center that weekend, so lots of fun writers.)

There’s also this page. And the White Eagle is right off the yellow line, and a cheap, rocking place to stay from what I hear.
