tent and weather in Uganda and Tanzania

I will add some questions:

When going to Safari and on hikes, what are the accomodation possabilities and what are the prices for each of the case?
Will a tent save a lot of money, or is it a matter of only few dolars every days ?

In case that we will take a tent, are the ususal camping places covered, so that opening a normal (not waterproof) tent will be enogh ?

Thanks a lot.

I can only speak for Tanzania. On Safari, all camping gear will be provided by the tour operator, same on Kili treks. If you plan to do any treks in more remote locations (e.g. Udzungwa mountains), you will need your own gear.
Tha camps in the game parks and on Kili are very basic, so certainly not covered. Outside of the game parks and tekking areas, you don't really see many people camping, although it is possible at some guesthouses to pitch your tent. Otherwise cheap guesthouses are the way to go, no hostels as such.

Uganda has cheap hostels, otherwise there are cheap hotels everywhere, not worth dragging around with a tent.

You should consider taking a tent. I took one myself and it was a good idea. It saved me some money but more importantly it allowed me to go anywhere I Iiked, whenever I liked. No bookings and no planning. Not everyone wants to share a dorm either especially if you are a couple and cheap lodgings can be dirty too, I had a few problems with bed bugs.
I camped in Kibale NP to see the Chimps, the lawns were well maintained and it was easy to escape those bloody overland trucks. The restaurant was great, the staff were friendly and the guides first rate.
I also camped in Queen Elizabeth National Park because the hostel was fully booked. Although it is not as interesting as Murchison falls, it was fun to camp and shine my torch into the night and see the eyes of 2 hyenas looking back. In the morning there was also fresh lion prints nearby too.
Camping was also the only way to stay in Budongo forest. We saw chimps but not close up.
Take a simple dome tent. Between two people it is hardly a problem. They are cheap and it doest matter if you leave it behind. It must have a fly sheet and do take foam mats. The biggest advantage of having a dome tent is they are self standing and you dont have to peg into hard stoney ground.
I do hope this helps.
