What theme park would you recommend?

My fiance and I LOVE roller coasters and theme parks in general, and we want to go to one on our honeymoon next year. We're looking to go someplace new and different, though, since we've both been to Disney World, Universal, Islands of Adventure, Busch Gardens in Tampa, and Six Flags Over Georgia. Do you know of any other great theme parks with plenty of roller coasters (Disney really doesn't have enough of those)? What other theme park(s) would you recommend?
