COP was open the Thursday before President's day, but not the Saturday of Pres w/e. However, Timekeeper was open that Saturday, but closed at 5.
If you notice either attraction is open, get on it ASAP. We found out that the Thursday we went on COP that it'd been open for an hour (at 4ish) and they were going to close for the day relatively soon.
I hope both open while you're there, Pattn. My kids are now understanding of mom and dad's obsession when either attraction is open and humor us. I've caught my 3yo singing "there's a great big beautiful tomorrow", so hopefully this means another generation will badger the powers that be to keep COP open!
