Minigolf Adventurer Achievement
Complete Traveler and Explorer courses in 12 under par.
Simply beat the First Tournament "Traveler" and Second Tournament "Explorer" with an ending score after day 2 of -12 or better. This really isn't hard at all, but may take a couple runs to get used to the holes. You also can save after every hole and reload the save file if you score poorly. Look for shortcuts around the hole.
