Hello Everyone, I'm very thankful Reddit exists right about now.

I've made plans to Olympic National Park for my brother's 22rd birthday and will be camping out there for a couple days. However, since some campsites run on a first-come first-served basis, I'd like to ask for advice in case there are no sites available in my itinerary below.
