You can ask at the hotel, but what is an upgrade at Quality Inn?

I was with my brother who flew in from PHX and we were on the same last flight of the night from DTW YYZ which went MX. I was given Westin room and he was given some dump due to no status. He came with me to the Westin and with his SPG and my voucher we got the two bdrm suite for an extra $50.
