This indoor putt-putt course is 18 holes of black light, glow in the dark fun for all. It is great for all ages. My husband and I love it and we even have taken our nieces/nephews and they love it too. It takes between 30 minutes and an hour, depending on how busy it is and how fast or slow you want to play. It is not your average putt-putt course and the staff is easy going and friendly too.
