I went ahead and updated the Wiki to show those who are definite. We're now at 14, most staying Friday, Saturday, and Sunday evenings.
We can definitely drop to 4 sites and 4 meals, so Sunday dinner can be scratched, which will be better for Katiesue and company. Speaking of which, I switched you to the breakfast that became available due to an entire team dropping out.
We can also possibly drop Thursday and Tuesday, thus bringing the cost down even further.
Stay tuned - NA is working on the semantics.
