itrUganda-Rwanda-Burundi transport

Hi all!

I'm based in Addis Ababa, and thinking of making a short trip to Uganda, Rwanda and Burundi in the beginning of 2012.
A lot of time i will not have unfortunately, i might even be restricted to the capitals and in Uganda and Rwanda a couple of places.

I was wondering if anyone can give me an estimate about traveltimes of buses between:
Kampala-Kigali
Kigali-Bujumbura.

Thanks in advance!

There are daily departures for each of the two destinations. It takes about 8 hours for Kampala-Kigali, and 6 hours for Kigali-Bujumbura on a coaster coach such as Yahoo or Belvedere. Clocks go back one hour in Rwanda when coming from Uganda.
