If you are young, single and looking to party, there is no better place than the Hard Rock Hotel & Casino. It's social - big time. This is not your Grandma's casino. I'm not saying you'll be uncomfortable if you're NOT young or single, but if you are, definitely spend some time here.
I particularly enjoyed playing blackjack at Hard Rock, but even if you're just there for the scene (not the gambling), you'll have fun. The music was loud
The only downside? It's off the Strip so you'll need a cab to get there. Cab lines to go elsewhere tend to be long so allow sufficient time to get from here to there.
