This is definitely a "rustic" experience. This is held at a church camp and there are cabins which you share with roommates. It's a great way to meet or hang with friends. It's not ideal for couples... Genie and I typically stay in town (Prescott). Last year we actually stayed in the hotel at which the dinner / dance party was held and that was great because we didn't have to drive when the part ended (we closed down the dancing, of course).
Food is standard cafeteria quality food. If yo are picky, you can stay in town. But if not, staying in a cabin and eating in the dining hall makes this one of the most economical events of the type you could go to. Basically, once you are there, there's no need to spend any additional money at all.
