Yes, this casino is located in a not so safe area just stay in the crowded areas and you will be fine.
Rating the rides, I can say from experience that they are only scary if you have that fear of heights.
X-scream- will make you grip the handles for your life.7
Insanity- gives me a headache more than anything.4
Big Shot- will give you the highest view of the city.8
I also highly encourage jumping off the top of Las Vegas for $100. It was a definite experience, although should be priced down a little.10
The Stratosphere also has the only European Pool that offers the best view of the valley and mountains.
Not to mention, the cheapest in town. (Opening this spring)
