I’m just letting you know someone read your question. I don’t have a good answer though. 🙂
My gut would say don’t take 2 weeks off. I think a couple days for Thanksgiving wouldn’t be a big deal. You might be able to get away with a week at Christmas but it would make me nervous being only a month away from your final meet. I had two girls this year miss full week mid season and they both did very well at Sections. So I think it’s definitely possible but I’d still get at least 3ish practices a week during Christmas break.
Not based on any science. Just my 2 cents.
