Any advice for a divorced parent about to deal with school holidays?

So I have primary care of my daughter and she see’s her Dad every 2nd weekend, he lives 3 hours away.
She’s starting school next year and he wants to split every school holiday up – so I have her half and he has her half. I’m dreading it and I guess a week with me and a week with her Dad will be fine for her – not me. However it’s Xmas I’m worried about. Those holidays are 7 weeks, I’m not ok about her being away from me for 3 weeks, also he works full time. How do other parents do it and does it work for the younger ones who are with one parent full time?

She will be 5 of course but she’s only ever been away from me for 4 days at the most and at the moment she normally calls me every day from her Dad’s asking if I can come and pick her up. He dials the number of course – (she’s 4)
She’s happy there, he’s a great Dad – but my daughter and I are really very close and I’m not sure being away for such a long time would be great. Your thoughts?
I know it’s not till next year, but I’m thinking about it now as I need some time to come to terms with it all.
