I'd like to make a few comments / questions regarding pool instructions generically.
Before I do, I want to say that what I'm about to say is my genuine feeling, and in no way meant to belittle, demean or in anyway downplay pool instruction, because I'm fully aware that for some percentage of beginners and those entering intermediate ability, personal instruction is a great catalyst for jump starting a deeper interest in the game, which in turn opens doors for learning.
I see the oohs, and aahs, here by posters showing interest and wished they could attend. I'm so very curious about the speed of the folks who are interested as it is my firm belief that the better you are (read B player or higher) the less you will get from this type instruction. Conversely, the closer you are to C or D ability, the less aware you may be of the many options available to learn about the game on your own.
I think that the only "UNIQUE" benefit that comes from personal instruction (unique in that you can't be taught it any other way) is that the instructor can guide you on your body mechanics specifically, and that's it. That's certainly not to say this isn't a very important thing, just not something that lends itself well to group instruction.
To wonder, or want to share what is taught, is next to useless IMO because if it is not specific to the players "form" i.e. some flaw that can be corrected, no other information could possibly be shared that hasn't already been written about, recorded on DVD, and is readily available for sale in any number of places. Not to mention the tons of available match games that allow you to watch and emulate players stance and stroke.
In fact, spending 1500 bucks on DVDs, and books would, again, IMO be a much better choice than any group lesson, since you can revisit those instruction over and over and over again. And you can resell them when you are done with them.
Being able to replay instructional DVDs, re-read books on pool,and then experiment with your new information is the way to sink it into your brain. IMO it certainly isn't going to sink in during a group lesson anywhere near as well.
