Well, Dean...it depends on your level of OCD, and ability to cope with it.
As a friend and professional shooter once said, "You're in trouble when you stop playing, and keep taking pictures."
That has not happened, yet, but it's tempting.
I generally take a photo of the card at the beginning of each hole, for reference.
If the tees shot looks interesting, I take that. If the approach is good, I take that, too.
If the green has interesting angles or features, I take quickies of those, as well.
Basically, when using a point and shoot, I document my round.
Hold the camera high, and give yourself as much elevation as possible.
For casual shots, try Sony's DSC w-150, a point-and-shoot w/ the equivalent of a 28mm lens. Don't worry about zooms on such cameras. Take wide over long focal lengths.
For more serious shooting, I carry two lenses with my Nikons. The most versatile is an 18-200 mm zoom. Very crisp.
The second is an 11-16mm wide angle from Tokina. It's the first non-Nikon lens I purchased 55 years, and worth every penny. This is a helluva lens. Have stood on top of carts, looking down with God's Eye Views.
Bottom line...if shooting becomes part of your pre-shot routine, nobody notices. I might add...the photos are better without people, however, so pick your moments. Walk fast, or linger just a touch.
Lightroom works wonders.
Here is a link to some of those casual shots.
