The casino is great for cheap craps ($3 min w/20x odds) and their $50 slot play (promotional machines only). No valet parking and the parking structure smells of trash.
Getting into the casino property can be difficult because of all of the people walking, but be aggressive and you'll get in. It's next to Harrrah's so it may be better to park there and walk to Casino Royale.
It's not the nicest place on the strip, but for cheap gambling and drinks, it's a good place to go. Be sure to get your players card for the promotional $50 slot play, 2 for 1 Ben & Jerry's, 2-1 Michelob, and 2-1 Blackjack coupons.
They also have a Tix4Tonight inside. It's a great place to get discounted show tickets.
