Nice little local blog - do you know about Guestmob?

Update, in a tweet from Scott @PDXtraveltips:
@ElainePDX @Guestmob My guess is Guestmob good for advance bookings, Priceline still king for last minute.
Still, I was happy to learn about Guestmob since it does have some advantages over Hotwire and Priceline.
