Do you suggest listening to an entire course in one sitting, making for a say 6-9 hour session?

Won't your bum get sore from sitting?
sorry, mine does!
Only joking Michael.

Do a course in any way that works for you and your schedule.

However, you will probably receive more benefit by doing the sessions on different days. Incubation and integration plays an important role.
