i haven't heard of any such req. i read online that the tourist is expected to need $50USD a day. but i came here w/ $350
and have most of it. but that's because i'm staying with friends. that $$ is for souvenirs, to contribute to the (internet) bill and whatever else. i will have to use more $$ to make the historical tour to Axum. one place quoted me a price that more than it cost me to get here from the US(!). anyway he he later gave me the Habesha price, so i'll c about going.
