Hi all. I am comped for two nights ( a Monday and a Tuesday) in a basic king. I will be staying alone and I will be trying for an upgrade with either 20$ or 50$. My question is what room/tower/suite should I try for? What recommendations can you give for solid rooms at the Excaliber and also what should I try to stay away from? And don't say the hotel itself. Free is free and I'm not an elitist.
