the Millenium through Priceline in 2010 for $35 or $40 and thought for that price we'd give it a try.
As we were checking in some flight attendants were leaving and we took that to be a positive sign. When we arrived at our room it was not clean (carpet stained and musty, moldy smell) - some tiles in the bathroom were missing and the "headboards" on either bed looked like rubber floormats stapled to the wall. The bedding looked soiled and some dresser drawers didn't have any knobs.
In fairness, the staff at the front desk offered to find us another room; at that point I just wanted to leave. We did. We drove to the Holiday Inn Express (where we ALWAYS stay) and stayed the night there.
We wouldn't go back to the Millenium, for any price. That's our experience, for what it's worth - I've read some favourable comments from others .... so maybe it was just "bad luck"
