So, did you like it long? :-) I had a back-to-back session each week instead of twice a week and I really liked the time so I didn't feel like I was just getting started and the session would be over.

Good for you wanting to take more responsibility for the sessions. Don't forget though that it's a whole process and no single session is "that" important but all works together, accruing benefits. And sometimes what seems not to have been very good can become good over time as new insights happen.
