The master theme camp/village list.
Unless it has changed, its an alphabetical listing with a brief description supplied by camp organizers.
Food, shelter, etc are furnished/not furnished on a camp to camp basis. I'm sure most, if not all, will have at least a communal shade structure of some sort for the main interaction areas.
You will want your own personal space as well, which will need to be shaded and set up as if you are camping solo. Radical self reliance does not end because you joined a camp. You are talking up to a week or more in a harsh desert environment with other people in close proximity. Fatigue, heat and the host of other daily trials of the environment and how you are physically and mentally impacted by it are the perfect catalyst for building friction and irritation among camp members. Most of that can probably be overcome by retreating to a personal space to refocus yourself, but in case it can't, the option of having the gear necessary to move out should be planned for.
The camp I am in will have (well...I think we will) a basic communal kitchen type area, but meals, what you want to eat, etc are up to the individuals. That of course does not rule out organized pot luck dinners or sharing meals with others, etc. Planning, preparing and serving up meals for 30 to 100 people 2 to 3 times a day without having the necessary experience in the kitchen is a recipe for disaster. I can manage cooking for 10 to 12 without a problem, but you are eating my menu of what I know I can cook on that scale.
I guess what I am trying to say is plan accordingly. Even if the camp you are in says breakfast and dinner included in camp dues, you might seriously want to consider bringing your own anyway. Keep it limited to fast and simple meals, like backpacker meals or similar, but bring it. If you are the lone voice of dissent objecting to the seasonings or ingredients that 40 others think are perfect and tasty, you may be told to deal with it or go hungry. Harsh, yes, but if it were my kitchen, its probably what you would hear.
Also, KP for that many is no fun at all. Sure its (well...it should be) a rotated responsibility, but cleaning up after 50 people is still a tedious process that occupies your time.
You will probably incur additional expense over the ticket price and your own gearing up for the event. Theme camps and villages have infrastructure costs that are typically defrayed by all of the participants of the camp. If you are in a bar oriented camp, like I am, you have the basic infrastructure costs that all camps have on some level coupled with the cost of stocking and running an open bar for the masses. Also, since we are an alliance of camps, there will be some shared expense over and above the individual camp for a much larger infrastructure serving multiple camps.
