Well, I am the course coordinator and I wouldn't necessarily play a round of glow there by myself, but I wouldn't be too concerned if I were playing with a group of people there. Sounds like you will be alone though. Since you will only be playing a couple of holes right after dark I wouldn't worry too much about it.
It is a great course, and I recommend you check it out. If you are concerned about being out there alone, I only live a few blocks from the course and would be willing to meet you out there and play a round together. Having a guide on a new course might help you cut a couple of strokes off your round.
Let me know if that is of interest to you.
