To answer a couple of your questions that haven't been addressed: What an open water certification from any agency gets you is the ability to get air fills, rent scuba equipment, and go out on charter boats. I have never gone anywhere where a dive operator hasn't wanted to see some proof that I had passed a training course. A couple have wanted more than an open water cert in order to allow me to do certain dives (particularly deeper ones). Yes, an open water certification will let you go places and see LOTS of cool stuff!
How long will it take? A lot of classes are given over a single weekend. My OW class ran over three weeks, with six classroom and pool sessions, and two weekends of OW dives. I think spreading things out that way helps you do some mental integration between sessions -- but at any rate, you can easily finish an OW class between January and April. The only problem with that may be where you are, as it may be hard to find someplace to do the open water dives at that time of year. (I don't know, and that's something to talk to a shop about.)
Now to my opinion: Have you ever gone skiing? Skiing is tremendous fun . . . when you reach a certain skill level. Before that, it's pretty much frustrating, and you don't get to go to the cool places on the mountain, and you don't see very much. Plus, you're a setup for an accident, especially if you end up on a run you didn't realize was too hard.
Diving is a lot like that, except the stakes are frequently higher. As a brand new diver, you're often so preoccupied with simple executing the mechanics of diving that you don't see very much. In addition, with poor diving skills, being down there is a lot of work, and your tank doesn't last you very long, which means you paid $150 for a dive charter in order to enjoy a couple of 20 minute dives. In addition, a poorly trained new diver encountering ANY kind of problem during a dive is a setup for an accident.
The way to avoid that is to get good training. Spending a little more money and a little more time on a class that gets you more pool time (more PRACTICE!) and more attention from an instructor, puts you into the water on that Cancun trip more relaxed, more capable, and prepared to have a lot more FUN.
Just my two cents' worth . . .
