Not anymore. But I do remember seeing the roller coaster ride running in 2004 😨. It was closed down in December 2005 and I believe it was costing over $500,000 to repair it. Thus, The Strat Management team decided to remove it. During that time, Las Vegas didn't have extra money like that. They did end up replacing the ride with X-Scream. It's not as scary as the Rollercoaster. However, it's very popular.
Btw, the Big Apple Roller Coaster in New York- New York Hotel and Casino is much scarier and faster. You can see the whole Las Vegas Strip along with the live traffic up close. It's scary!
