Which Vegas casino has the rollercoaster?

There are 4 on the Strip: The NY NY and atop the Stratosphere. Both are great but the one on the Stratosphere (not sure if it's been removed however), really gets your pulse pounding (IMO). One in Circus Circus, under the big top and one at Sahara too. Have fun.
Also there's one in Primm, NV at Buffalo Bills Casino/hotel called the Desperado. At one time it was the 2nd tallest in the nation. A fantastic ride that won't be forgotten. It's about an hour's ride outside of Las Vegas, off I-15, approximately 40 miles.
Check out the websites below.

New York New York, also I think the Sahara has one.

New York New York and the Stratosphere.

New York New York has one, and the Stratosphere has I think 3 rides.

Strashophere has one on top about 1000 feet above ground

New York New York, Sahara, Circus Circus, and Stratosphere all have rollercoasters.

Buffalo Bills has one too, but that is near the California border.

The Stratosphere rollercoaster "High Roller" was removed a couple of years ago

The Stratosphere still has rides, X-Scream, Insanity & Big Shot, but High Roller was removed in December of 2006 I believe

NY NY - Manhattan Express
Sahara - Speed
Circus Circus - Adventuredome "Canyon Blaster"

Not a rollercoaster, but this would have to be the greatest ride of all time, if you have an extra $3,500

NYNY has one. ..... And go to Primm the place down there has a hugh one.

Don't forget the Desperado in Primm at Buffalo Bills, worth going if you like wood rollercoasters.
