My T takes 6 weeks of vacation every summer. First of them was okay because we had just started couple of months ago and I had not developed any attachment feelings yet.

Second year was terrible. We knew beforehand that it could be difficult and we agreed beforehand that if things get too difficult for me then I'll email and we'll schedule an extra session during his holiday. It turned out to be necessary.

Next year I was leaving the country for a year in the beginning of his holiday. As I was alone in a new country with new job I developed terrible anxiety that was completely unexpected. So wrote him couple of very desperate emails answers to which I waited like they would be my lifeline or something. As he didn't respond quickly enough I ended up looking for a local T which proved to be a great decision.

This year my strategy is as follows: I will take my pillow cover with me (Couple of weeks ago T offered that I could take it with me for weekends which I have been doing). I will also email if needed. My T normally doesn't respond but when desperately needed I can explicitly ask him and then he does. I don't believe I need to arrange a permission to call or have an extra session this year but as I said, these have been used previously when I truly needed such measures.

My T brought up all these measures or at least initiated the discussion of how I will cope or what I need in order to cope. For me those measures have been very helpful. I hope you'll be able to negotiate with your T what you would need and what she can offer.
