Know the heavy windows
Memorial Day, Independence Day, and Labor Day are the big three for parks, while winter holidays and Presidents' Day weekend dominate ski season. School breaks stack on top of these.

Lodging near popular destinations fills months ahead for major holidays. If you did not book early, pivot to a less famous destination that absorbs demand better.
Time the edges of the weekend
Arriving the day before the rush and leaving before the return wave can dramatically improve a holiday trip. Early mornings remain your friend throughout.
