I am guessing most theme park places are going to have reservations .. no huge downside to it as I doubt a lot of these places are going to get the walk up traffic for a while. But it does make me miss the "simpler" times of grabbing a Coke can (for the discount), hopping in the car and driving 60 miles south to Six Flags Great America.

. That was a LONG time ago though.
As I am looking for some sort of more local "replacement" vacation since we have to cancel our mid-June Disney trip, I am still waiting to see when things in my state open, like Tweetsie Railroad, Carowinds, or the NC Zoo to open, I think those are technically allowed to open in "Phase 2" (which we are in) but i haven't heard of of those places announce an opening date yet.
