I misunderstood your concern. I thought you meant a week a month. Look up step up custody plans,which would be something like you are talking about. However, standard agreements usually allow each parent a certain amount of time for vacation each year. But here is where I get confused.
How is a US judge going to enforce a custody agreement in Europe? So, if your H says I want to take her to Pazis for a week for Christmas, and you say no, how does that play out?
In many divorce decrees, there are steps laid out for when parents disagree. Sometimes mediation or arbitration is ordered. You are in Europe, he is here. YOU have all written permission and a documented custody agreement that gives you the right to raise her in Europe and you need to get control of her passport spelled out in the agreement as well. (You get/have to have it). BOTH passports. Can a US Judge order you, in Europe, to do something? I don't think so, but check with an attorney.
I know you want to be cooperative, need to be cooperative for financial reasons, and frankly the vacation/Disney dad is just part of the sh*t sandwich that is divorce, but the key thing here is making sure that all bases are covered so that you are protected and your D is protected.
