I've played some pretty cool mini-golf courses in my life, Hillbilly Golf in Gatlinburg for example, where you have to take a tram to the top of the mountain and then play the course to the bottom, and Mulligans in Salt Lake City, which has lots of waterfalls. But my favorite golf experiences are Putt Putt Courses. If you don't know the difference between these two types of golf then you've come to the right place.
First off, Putt Putt courses are always a Par 2 for each of their holes. There are no extravagant designs, in fact, they are pretty minimal. The point of Putt Putt is to understand the angles, and use skill, as opposed to the luck needed to navigate the unbelievable obstacles that you find in mini-golf. Putt Putt challenges are usually limited to small hills, pipes, very rare water hazards and metal blockers. Mini golf is usually theme based, (Pirates, Dinosaurs, etc.) and is more luck-based by design, In mini golf, your skill in putting is substantially less required than for you to have a healthy dose of good fortune.
Plus, me personally, I just like the minimal layout of the Putt Putt courses. I like the square overhead lights, the awesome orange paint and the overall clean look of Putt Putt courses. And it really is you against the other players in your party, versus you against the windmill, clown teeth, T-Rex's tail, etc. And have I mentioned that skill is much more in play than luck in Putt Putt?
It seems bizarre that in most things in life I love the craziest, most imaginative, fun experiences possible, but not when playing mini-golf. What that says about me I have no idea . . .
