The Royale is no longer a good bet. All full pay video poker has been removed as of june 2013. They also made comp rooms much harder to qualify for, but with no good games to play anyway, its only good for drinking cheap and slots. And if you play slots why play there. The cheap rooms and better games are now in the north strip area.
Casino Royale is really only good for one thing - cheap drinks. $1 Michelob's or $1 Strawberry or Lime Margaritas. This, you can not go wrong with. I usually grab a couple brews and the ponder over the TIX 4 TONITE screen to see the show deals.
I joined the slot club for the $50 Slot Play - It's a voucher for a promotional machine that I think only 1 person wins on in a year, not worth your time.
Avoid the hotdogs at the back of the casino, there is a reason why they are that cheap.
Staff is generally rude here, then again, it's at Casino Royale. I would not be happy if I worked there.
So, as I said, use this place for only a pit stop to re-hydrate yourself...
