They last day of school before Winter/Christmas Break is Friday, Dec 22, 2023 for most public schools in NJ this year, including my district, the district my daughter teaches at and the district my grandkids go to. Since I have quite a few friends in eastern PA, I believe they are on the same break schedule for Christmas as well. So, I'm going to agree that there will not be a ton of kids unless they are traveling from different areas or attend local private schools that get out earlier. Definitely less than Christmas week.
