All,
As I posted in the Intro area last month, I plowed thru my 4 OW dives & 5 AOW dives in a three day weekend.
The arguments against doing this seem to be along the lines of "you won't get much out of it" and "for safety's sake, you should get more experience".
I have no problem with either statement, but since I live in Colorado, a dive trip is a big deal. It didn't make a lot of sense to me to put off the AOW cert just because it "allows" me to do diving that I "shouldn't" do.
I'm a fairly cautious guy. I look before I leap. Although I hold an AOW cert card, I'm going to dive within my comfort zone.
As long as the original poster is doing OW & AOW together for convenience, rather than to do advanced-type-dives right out of class, I'd say there's nothing wrong with it.
