I'd like to comment on the original post of getting your PADI DM in one week. This subject probably does not need alot more commenting on but...... I recently did my DM in the Philippines, and did my pre-study before hand, without said, I was in the water to some degree almost everyday, and if not in the water, doing some studying. I'll admit we took some longer lunches and it was not 'pedal to the metal', but anything more intense would have been more 'boot camp' like in comparison.
In the end I completed the course in about 32 days, including tropical storms and several 'give me a break days', altogether we did close to 40 dives as well.
So becoming a DM in one week, you might want to look around at some other dive shops!
Then again that's just my opinion!
