Links v Parkland - my observations.
I've been on vacation for a week and have now played four links-style courses (in North Wales). First time ever and I wondered about the differences and impact. So this is a 21 handicapper's view
Short answer: Not a lot of impact on score. I broke 90 on two of them, and stayed below 100 on all of them. Fairly typical for me when visiting new courses.
Long answer: You can get some serious distances off the tee. I beat my all time record at North Wales Golf club with a strong tail wind - got 320 yards. Then dropped the ball a foot from the pin from 120 yards and walked off with a birdie (probably a seagull ).
Downsides - a lot of the time you can't see where your ball comes down because a hillock or gorse bush obscures the view. Also - because of all the bumps and stuff - your ball can do some odd things when it does actually land.
The bunkers didn't bother me other than it being ridiculously easy to get out of them. My biggest problem was avoiding sending the ball right across the green.
Other than that the greens on the North Wales course caused me problems (long putts and chips were fine but short putts went awry).
In conclusion: Links are different..but for a high capper at least the score is much the same in the end.
Addendum: One hole on that North Wales Club was really freaky. From the tee you couldn't see where the fairway was. Ahead was just scrub and a stream. Eventually I took a gamble and aimed for a fairway I could see but I still don't know if my ball actually landed on the correct fairway. It was certainly a fairway but what hole it belonged to I have no idea. I launched off it and landed on the fringe of the correct green so..meh
