ok, so got a few mins free to get some of the info up for you - I don't have very precise data to hand but hope some of this comes in useful maybe.
Syria - Allepo is very nice, castle is well worth a visit and food in the town is grrrrreat! there is a very nice campsite about 20Km west of the town run by a Belgian lady - you may well pass it and there is a sign pointing to it from the main road. try a google see if you can find it or use T4A
Damascus is also a very cool city and we spent a good few days there, again great food and loads to see.
East side of Syria also very beatiful in a deserty way, wild camping in desert near Palmyra is good
Jordan - Wadi Rum is superb, and there are a few campsites south of Aqaba on the coast, not the council run ones on the beach but on the other side of the road. Snorkeling is good here!
Dead seashould also be visited - you can camp on a car park for a mountain top historic religious site (forgot name sorry!) you just need to ask the tourist police there.
Lots to do in Egypt - worth going across Sinai to Dahab to do some of the worlds best snorkeling, you can camp at Crazy Camel
White desrt is very cool, as is the rest of the Oasis circuit, but the police can be arses sometimes - they dont like wild camping and are obliged to provide tourist protection, so if you dont have the name of a hotel to go to or wont let them take you to one you may be chased out of town - we were twice.
Sudan is a bit dry for campsites - after Wadi halfa there aint much, but we id some real nice camping in the desert in the north, had a shite camp in Blue Nile sailing Club, and stayed in a couple of cheap hotels after that.
Ethiopia - gonder is a nice town, before you reach there head for Tim & Kims on the side of Lake Tana - real cool couple and a very nice place to chill.
We camped in the car park of a hotel in Gonder also.
We didn't get into the simian mountain nat. park as they insisted we took a guide, so drove a very long and very rough route round to the north of the country. It is a bit wild out there and nowhere to camp, so when you see an option, take it. Axum is a nice town and the manager of the Yeha hotel will let you camp in thier grounds - nice place. for the remainder of our circuit of Ethiopia it was hotels - quite a few of them, and again if you see soemwhere that looks good take the option rather than pass it hoping to find another as its very hit and miss there. In Addis Abbaba then you need to get to the train station and look for Holland House - very basic camp but ace pub : ) Addis is an interesting city and an eye opener.
there are lots of historic sites to see in Ethiopia, but as mentioned by others, dont underestimate how bad some of the roads are and how long it can take to travel seemingly short distances!
In kenya we stayed at a cool campsite near marsabit - swiss henrys - you'll need T4A to get you there. And further down near mount kenya there is a very nice camp/lodge at Timau lodge - it's on the road that curves to the east of mount Kenya after isiolo - great sofas, currys,
s there in a lovely setting.
kericho was great - you can stay in the teea plantations at the Tea Hotel - dont miss this place as it's a gem - fantastically old fashioned british plantation hotel which was built by Brooke bond and they have a nice camping field next to the gardens.
Masai Mara - crocodile Camp was the best we found.
Twiga Lodge on Tiwi beach south of Dar Es Salaam was tres cool and you can camp on the beach.
having to go quick now as battery going...
In Tanzania, there is a camp site south of Tanga, Peponi beach - very cool and the countryside is beautiful.
On to Dar and we are really enjoying Mikadi beach campsite which you have to take the local ferry across the sound to get to - again beachside camping. Easy 2 hour ferry journey (without bike I'm afraid) to get to Zanzibar where you should stay at the dhow place hotel in stonetown if you get the chance - cheapish and fantastic!!
thats all for now from me I'm afraid, powers going and it's my round - HAVE FUN!!!!
