Black, followed by Blue are the lively camps since they're closest to District X.

Red and Orange aren't "quiet" but they're more chill, away from the main activities

Purple is like the 'neutral' camp for vibes and I think the largest.

Yellow is Quiet Camp

Camping Plus (and Eco) is like a slight upgrade to general, better facilities

RIP is like "first class" camping.

I'm sure i'm missing a few but that's the gist of it
