Thanks Okie,
Your valid points but I was referring to people in similar situation as mine, with full time job, wife and kids. I have my own airplane, passed my written and had friday, saturday sunday available every week.
The flight schools wanted to charge me 10 buck per hour extra for using my own airplane. I kind of had a bad luck with finding a matching cfi. Many a times, despite week advance notice, CFIs were not available for number of reasons, it would be a football game, a charter flight, wife's birthday, family vacation, you name it. Every time, I switched CFI (since first was gone for extended time), the next one had to "make sure I was able to fly the airplane" so he had to do everything all over again (including first 2 hours of finding out where I was in IFR training). My fourth CFI, did the same exact thing. After 70 hours of hood time, (60 hour with instructor), DPE told me the 8710 was not filled up correctly (my cfi was in a different state on a charter flight). Obviously, had to pay the examiner, get hold of the cfi next week for sign off and reschedule the check ride.
It is just a personal opinion but when I look back, it would have been lot easier if I had gone some place for 7 days and gotten most (if not all) of it done in one shot.
