I wish I saw this thread earlier. Had to do a last minute trip to PDX this weekend, and staying at the Airport HGI. Got a good rate, staff friendly, and recieved coupons for continental breakfast (restaurant not open on weekends).
I've never had a problem with housekeeping rifiling through my stuff. The desk usually has a mountain of "stuff," including read and unread newspapers, empty water bottles, papers, reciepts, change, etc. Nobody ever touches it. The only way anything gets tossed is if I put it in a trash can.
