MSS, The Cal, or Fremont

[aliasyoshi]

I need some help from you guys and gals to decide between Main Street Station, The Cal, and Fremont for a 3 night stay in January. I am very familiar with downtown and each of these casinos, but I have never stayed in any of them. They seem very similar from descriptions and reviews. I am going with a buddy of mine and we will be using the room to sleep in and that is about it. Just want a decent room that is clean. Any opinions?
