I wish you luck with your new therapist, as I know these transitions are not easy at all. I would ask about the vacation, since its that time of the year, also about boundaries, and contact between sessions and such. You know its a get to know you kind of thing again and you only have a hour to feel your way through this, just to start, you will be able to tell if you feel ok about it, you get vibes.
I hope it goes well for you, and this therapist is in it for the long haul and you wont need to transition anytime soon, thats what I am hoping for me as well.
