I worked in the ZOne as a “specialty” and had plenty to do with the campers! Although i didn’t work in Negillah i was there a couple times and can say, from what i saw the difference was the ruach. In negilla the atmosphere is extremely homey and cheery, because of that it doesnt matter yeshivish you are!!) It seems everyone is friends with everyone and no one is judgmental. The Zone on the other hand is more professional run, so even the fun is “proffesional” (ie: grand trips, concerts, ect…)
