What's the best time of year to visit with the least attendance to avoid long lines but still have all attractions open?

It's not a 100% rule but our experience is, if the park is not staying open until midnight they don't expect a huge crowd.

Weekdays after Thanksgiving

When the kids are in school, it's not a holiday and the park stays open til midnight! Fall break last week was pretty bad.

Fast pass can be bought online too for faster line😁
