I don't remember the Sunset Station being difficult to get, but the Palace Station was on the craps table for a while. They would open the Craps table after 8pm, on certain days, if the dealers showed up, etc, etc. So it was a toughie to get. And since I didn't have my tetanus shots up to date I didn't spend too much time in the Palace Station.

I have no idea if they are still in use.
