Where can I find a shop to dive with for a few days and pay for the cert fee?
FWIW course went exactly as I expected. Just a PADI shakedown scam. Did a couple days of decent diving but I’m going to be honest, AOW teaches exactly zero useful skills.
It seems that that was exactly what you were seeking - pay money, get a cert card, not actual training for an experienced diver. AOW does have value for the diver just coming out of OW with a total of 4 quick descents to demonstrate skills but no real dive exposure. The buoyancy portion was particularly useful for me as what I got in the 1-1/2 day OW cram-jam cert was greatly deficient.
There is NOTHING ADVANCED about AOW. It is part two of OW certification and should be labeled as such. All it is intended to do is give newly certified (not even lightly experienced) divers a slight bit of "get comfortable underwater" experience and some very slight exposure to stuff that is not covered in the kindergarten-level OW cert course.
As you said elsewhere, full OW should just encompass the 5 "adventure dives" that make one an "advanced" diver. If they wanted to keep the two separate there would be "OW-restricted" and OW-Full" and avoid a lot of the confusion surrounding the term "advanced".
Compared to getting a pilot license, OW is like getting signed off to solo: the student can take off, land, recognize and recover from stalls, perform basic emergency procedures, and navigate around a small, closed rectangular course. That's it, I would expect 7-15 hours of instruction. Not a full pilot until achieving private pilot license - more dual instruction and more varied experience: night flight, heavier cross-wind TO and LND conditions, dead reckoning navigation over longer distance, weight and balance calculations, radio navigation, more comprehensive radio procedures, WX/meteroology, more advanced emergency procedure training and practice.
