Dubious.
I'm not even a big gambler but the place is amazing. I can spend hours just wandering through some of the big casinos, sampling the food and drink without even touching a slot machine or a game table. What always impressed me was how quickly the place changed. Even a year later, there is something new to check out, whether it be a new massive casino, new shows or new restaurants.
It's not for everybody though. They don't call it Sin City for nothing.
