I used the course "250+ easy Achievement" created by Kinkyboots569. Using the pathway Play > All Courses >
> and entering "achievement" in the Enter Search Here field > Search - Course name, it was the first course that popped up. I hit the ball straight at full power, it appears as long as the ball goes into the ditch you'll get the hole in one, I got it on my first attempt. Quick and easy 90GS, feel free to leave comments or message me if you have any issues with the course or find a course that's even easier!
