On , I read the following:
"Regular meditation sessions are offered. These sessions generally can include meditation instruction, time for walking and sitting meditation, question and answer periods, and a Dhamma talk. Any one who wishes to go into days long meditation retreat, or come to the center for a few hours' sitting under the tutelage of two Sayadaws can do so at any time. It requires only to telephone ahead to set up the appointment time.
I would call, and ask that question at that time.
