We are normally camping because the chalets are very expensive and some not for self catering. A new camp opened in the western section called Dolemite camp. Its rates are very reasonable for single persons compare to KTP wilderness campshttp://www.etoshanationalpark.co.za/acc ... omite-camp
At Okaukuejo some of the chalets are not well equip for self catering and even lack a braai area, but you do get a fridge with tea /coffee stationhttp://www.etoshanationalpark.co.za/acc ... /okaukeujo
Halali will be better for self catering while at Namutoni you will be required to eat at the restaurants. Eating wise Etosha is much better than KTP, but the shops not great providing basic cooldrink, beer, wood and bread at least plus curios.
Onkoshi camp is also a new addition to NWR. We have not stayed there before but the location looks good. Only problem you cannot get there in your own car and need to rely on the park for game drives which is a bit pricy for me.
There are a number of private lodges and camping areas near the entrance gates at Okaukuejo and Namutoni so the options are wide. Some are not too expensive either and a good alternative.http://www.etoshanationalpark.co.za/acc ... koshi-camp
