It might work for you, it might not. It depends on your capacity to absorb information and not be overwhelmed by it. As a qualified British triathlon coach I’ve seen both sides, week long training camps are common place and work well for some, but not others. Obviously with triathlon a lot of it is fitness based fatigue but some people really struggled with swim stroke changes, very technical and similar to golf swing changes.
For my own golf I went down the 1 or 2 lessons a week path for a couple of months to groove in some changes, and it’s worked well. The problem with a lesson every 2/3/4/5 weeks is the practice in between - it’s hard to self police if you’re doing something correctly. It may feel correct in your minds eye but bare no resemblance in reality (which is more often the case) A few weeks of consistent lessons and practice, aided by filming my own swing at the range (using a phone tripod, best training tool you can buy) and knowing what I was looking for whilst reviewing it constantly each session has really helped me groove in a significant change quite quickly.
I hit 300 balls on the range today — only hit the 8 and 9 iron and a handful with a new club
It’s a lot of balls and I was only trying to work on one thing — which I think I achieved as the number of flushed balls was surprisingly / pleasingly high. I will have another lesson in another week and if I’ve not mastered what I was supposed to be working on then it’ll be very annoying as I’ve just embedded some bad habits, after 300 balls ? But at least tonight, I feel confident and optimistic that there was improvement ??
I hardly ever go to the range as it’s such a ball-ache to get to, and on a day off (which I’ve given over to golf), I’d much rather play golf. I used a tripod as Boomy suggests. I would second the benefits of this 100%
As per the OP’s main point, I would certainly see the benefit of a 3 hour lesson…as long as it wasn’t a range-session. I had a 3 hour lesson twice - the first was on putting, chipping, pitching and full swing — this was excellent and v worthwhile. The second was all on a range and it’s a little too much
However, I feel like an intensive course wouldn’t necessarily be an awful idea for someone wanting to learn quickly. As there is so much to learn in golf, and I think an hour-long section on chipping, putting mechanics, green-reading, pitching, bunkers, full swing with irons, full swing with Driver, and course management / playing lesson could easily cover two full days and be worthwhile
