I think it's possible to have too many inversions, such as the case with Thorpe Park's Colossus (not a fan of the ride's big finale). To me, it depends on how well they're spaced out.
Knott's does a good job on their annual Christmas event, right down to the extras they add to the train ride. The goodies at Santa's Christmas Cabin are great, too.
Sorry about this, but due to issues we've had the past two years with participants not following through and creating drama and extra work for the site admins, we have decided not to move forward with the ChrisHanKwanSivus gift exchange.
^People like Dinosaur for their own special reasons. Even though I think the ride is, well, kind of dumb (most of it takes place in darkness that, no doubt, pleased Disney's cost-cutting accountants when it was built), I consider no trip to DAK complete without it. I still find it entertaining.
