What is fair for a child who is split between two homes for school holidays?

Hi All,
I’m speaking specifically to Christmas Holidays.
I live 220kms away from my daughter’s Dad, which is roughly 140 miles
Over the school holidays he has her for a week – which is hard for me as I have sole custody and he see’s her every fortnight for the weekend normally, so a week is heart ache. I want to plan ahead for Christmas Holidays, she loves her Dad, she always comes home happy. He wants to do week on and week off for 6 weeks but I don’t think the travel will be fair on her and I think that’s disruptive, I’d prefer 2 weeks at home then 1 week with her Dad – or a 10/7 split something like that instead of 7/7 – what do you guys think is fair or what do you do if you’re no longer with your ex but you live 3 hours away from them?
