A really great coaster. Can't say I agree with it being rough. I rode it in late August and found it smooth as silk. My only complaint would be its loading staff, who regularly allow the cars to begin their voyage with empty seats.
Maybe when I get back to Orlando in 2010 I will get another crack at Kraken!
That said, last week I was at Sea World and rode Kraken for the first time in a couple of years. What a delightful ride. The front row on this coaster is a real treat.
Personally, this used to be my favorite coaster, but I found it had grown a bit rough, when I rode it last summer. Perhaps that roughness explains its position in the bottom half of the draw. Still, its Orlando site ensures that it gets millions of riders each year, and with a relative dearth of coasters in Orlando, it looks good enough relative to the competition to remain the most popular of the floorless coasters.
The only straight-up comparison I have is with Magic Mountain's Scream, and Kraken remains smoother than that coaster, which went rough within a year. And Kraken's setting blows away the parking lot upon which Scream sits.
