Well me actually being in Vegas as we speak... I can tell you off the bat unforchantly SPEED IS CLOSED. I was so mad when I found this out, which was in the Sahara lobby... Also saw you were talking about desperado, truth is I went to Buffalo Bills yesterday, its a 40 minute drive from the strip, and SO worth it. Desperado has some fun drops. (in 1998 it was the highest/fastest in the US). It was open, as was everything else there, so you shouldn't have to worry about that to much. You should also check out the stratosphere if you want to. Good luck.
