Steven,
in my view you can ask the excorts to meet you where you want.
So, if you want to meet in a bar, then it be so and the escort will comply, I am sure.
erhaps you can even ask her or her agency to make a good proposal for a bar, if you are not familiar with the local set-up.
What I have doubts about, however, is your hope, to find an escort that is not becoming boring after a while.
To find someone like that I believe you must be pretty lucky.
If I were you, I would, forathat reason not commit myself to a longer period but rather prolongate each time that I still feel the woman is OK for me.
Greetings,
Concerned
