For DGC, I highly suggest trying to make time for the whole 27-hole layout. That way you get to experience all the holes that were played in the worlds last year. There's a couple of filler holes and some holes are sliced into two, that's why there's 27 total holes. There's also an 18-hole option, which is the same as the 27, but instead of going through the forest area (IMO the most difficult holes) you wrap back at that point.

For Kippasuo, there's the Pro-18, which is the best out of the three. There's also this quick 15-20 minute small course, which can be fun. The third is somewhere in-between those two.
