Ah, but if we start to compare specific rooms with entire hotels things become a bit more complicated.

For instance, I'll be staying at the IC BKK soon. I chose them over the Pen because I was able to book an Ambassador Suite for less $$ than a basic room at the Pen or MO or any of the hotels in your first tier list. So for me easy decision.

In general I think we ought to be comparing either basic rooms or median rooms or best rooms... apples to apples.
