To clarify...
2 hours a week is not remotely "intensive" for a PPL. 45 hours in two months would qualify as an "intensive" course, better described as a full time course, where you would be at the flying school 8 hours a day, 5-6 days a week.
2 hours a week (which would be two one hour flights + 2/3 hours associated briefing/debriefings) would be a "very low intensity course" spread over 9 - 18 months (or longer) depending on your rate of learning. Most people won't do it in the minimum hours spread this way, because of the need to revise and consolidate more often when flying training is spread out.
The length of your flights (and all aspects of your training schedule) will be determined by your instructor...not you.
Don't take any of this as authoritative...or any thing else you read on here. go to flying school or two and get them to explain all this over a coffee. At the moment, reading your comments, you are somewhat in the dark.
I am just beginning gathering info about PPl so yes, you are quite right, I am in the dark. But many people said that doing the course over a longer period of time consolidates techniuque and information better than the fast-track one as you tend to revise more often. I guess doing it in the course of a year would not be a bad idea either...
