I will not be lying to you when I tell you that I have never been on a roller coaster more awesome than this one. Never. Not that I'm a roller coaster connoisseur, but I've been on my fair share. Rock 'N Roller Coaster wins every single time.
The part about this roller coaster that is so amazing is the very beginning. There you are strapped in to the car waiting for the clearance to go. When it's time, the car goes from 0 to about 60 in maybe 2 seconds.
The other thing that makes the roller coaster awesome is that you can't really see anything ahead of you, so you don't know about the dips and turns until you are just upon them. And there are a lot of twists and loops. Another bonus is that the whole time they are blaring rock and roll music at you. Granted, it's Aerosmith, which isn't terrible, but I would like it if it was mixed up a bit.
The true downside to this ride is the line. For some reason, this one seems to have a difficult line that Disney has never quite gotten right. I've waited in line for 45 minutes when the little sign at the entrance says "15 Minute Wait Time". And you can never eyeball the line either because it goes inside a building, so you really have no idea how many people are waiting. This ride would get a 5 if it weren't for this one annoyance.
It's a short little coaster ride that packs on major thrills. 4/5 stars!
