You need to search for the best price on the internet and join Groupon or Ebates to get an extra discount.
Shilo Inn--Portland Rose Garden . It's quality enough that it doesn't feel skeezy but you can walk right to the Moda no problem! And, for PDX, I think economical with some sort of breakfasty thing under $100 with taxes/fees economical... especially when you can walk to food and Moda easily. We stayed in a King Room for $89 all in back in June this year for the Rob Zombie concert.
