Hi Aris,
after 20 seconds of my research I found out that ALL three privats I have checked will be opened on 23 December with several girls available.
I have only checked privatescort.cz, topprivat.cz and pragueprincess.cz.
I believe that there are many more options.
So why don´t you click several more keys on your keyboard and help yourself?
Obviously, the offer will be very limited during Xmas time.
