GA airports near Portland, OR

I'll be flying into the Portland, OR, area for a business meeting. The
location of the meeting is closest to KPDX. Just a little farther is
KVUO. KHIO is also reasonably close, though much farther than either
of the other two airports.

So, it appears my choices are KPDX and KVUO unless I want to drive
farther from KHIO. The advantage of KPDX is the availability of ground
transportation services. Rental cars, cabs, and even a commuter train
are easily accessible. The disadvantage is that this airport serves
the airlines and I don't want to be vectored way off course so that ATC
can fit me into the approach. I also don't want to wait on the ground
on my way out for an extended period before receiving a departure
clearance. (I don't think I need to reserve a landing or takeoff slot
at KPDX, though am not sure.) KVUO is the total opposite --
GA-friendly but few very few services and only a non-precsion approach
(an LDA, at that). (KHIO is a reasonable compromise, but looks like it
will take much longer to drive to my meeting place in downtown
Portland.)

I'd love to hear that my concerns with KPDX are unfounded and that GA
won't be mistreated there. Anyone flown into that area recently?
