Here's another idea: Play 1 and 2, then play 14-17. That's six holes, and you can decide if you want to play 3, 12, 13, and 18, for 10 holes, or just turn and play 18 for the seventh hole. Not to give you too many ideas, but you could also pick several holes in a loop (there are several short loop options like this at OP) and play them twice around, once silver and once gold. Finally (last idea for now), if you want to get down to the far side of the course, you could park down by the baseball fields, and play 11-13, then 3-10. That's also 10 holes, though it's the longer and more challenging part of the course.
I have a similar situation where I work a 5 min. drive from Wills Park, and can squeeze in 18 holes there on my lunch hour if I play fast. Some days, when it's hot or I just don't feel like rushing, I'll just play 9 holes there, such as 1-7, and then 17-18.
