Sorry if this is in the wrong spot, but a couple of questions I had; Planning to explore a few venues and would like to know which casino's cards I should get, and which cover more than 1 location. I think I figured out which ones mlife and Boyd apply to, not sure about CET or others. Staying at Circus Circus, so will get theirs. Is that the mlife? Also, is there any point in signing up in the casino before my initial check in? Thanks to all previous posters, I've already learned a lot.
