1) Go the second they open. It’s a less busy time. Rides are not crazy busy yet.
2) Come home, eat lunch, and take a nap at 1PM. A 12-hr day is too long; you need rest, the kids need rest. This is also the busiest time at the park. Longest lines, most manic time.
3) Go back at 3PM Then stay til they close. Again, a less busy time is the hour or two before close. Everyone else is tired but you’ll feel good!
Do this and you’ll wonder why you ever spent 15 hours at a park. Ugh.
