The start for the full is literally right outside the guard booth to the entrance of POFQ. From that booth you walk a bit south on the 2 lane road, turn right, walk over a bridge above a canal, and you are there. Port Orleans Riverside is next to POFQ, so it looks like your walk may be 1/2 mile longer at most.
The start for the half appears to be just past mile 1 of the full course. Same process to get to the start of the full, then walk the remaining mile north and then west along the 3 lane road to the start.
For those interested, a good place to meet would be by the guard booth on the access road into POFQ. From there it's probably 1/4 mile to the start of the full.
On race days I follow a rather quirky routine, which I developed a long time ago on game days when I was a competitive soccer player. My wife saw it up close for the first time last January when we ran the half together, and after a while she told me, "would you just quit that!" It is the manifestation of my worst compulsive-obsessive tendencies, so although I'm happy to provide information, I'll be going it alone race morning.
Good luck to all.
