Facilities and accommodation.
Accommodations at these facilities vary, but they're most commonly in a cabin with bunks and electricity. Certain camps may have a more rustic or outdoor feel, but still offer a traditional set of activities. Meals are most often served in a large mess hall, which become events themselves!
You'll be able to find out more about the accommodations during your interview with your Camp Director, who'll answer all the specific camp questions you'll have.
