I'm in the exact same spot
@llCoasterN3rdll , so I know how busy your schedule can be. Obviously you can't go on these massive road trips all the time, but you can try to work amusement parks into your pre-existing trips. The trick I used is that I convinced my family to take me to a park that's near a College I want to visit. So when I went to Iowa State, I hit up Adventureland on the way. When I went to Purdue, I went to Holiday World and Kentucky Kingdom. It's not too hard to convince them and only adds a day to your trip, if not just a few hours. Once we get out of school, then we'd be able to have much more freedom.
By the way, good luck with Cross Country and the ACT!
