Thanks to all for the great information.
We live in Columbus, and are planning on spending the night in Mason April 19th. I think we will take our chances and head over to the park early on the 20th to get in line for pass processing.
Also, this will be my first trip to KI. I just moved to Ohio from North Carolina. I've been to several parks on the east coast (Kings Dominion, both Busch Gardens, Disney, Carowinds, etc.) I love, love, love coasters. Any suggestions for my first experience at KI?
Thanks!
