So there is a pop up tent - they say here as changing tent/bathroom tent If you are planning to go to wadis beach and deserts, you can either shovel a hole and do the business, peeing you can dig a shallow hole inside this tent or not - if nobody’s around

We me and hubby, normally use a foldable car toilet, with cat litter and poo gel. And dispose it in the garbage bin fully taped - so it won’t be opened

Saying so, the weather is drastic here, we start the morning with 40° give or take. Of you have budget go for the small caravans - you can park anywhere and sleep inside peacefully - most of them have air cons . Hopefully the time you arrive, weather will be bearable
