The tourism business is mostly in english, even here in Hungary where lots of german tourist visit us every year. But i understand what you are saying. Now i would never consider living in Angola as good as it look in that video, they didnt show the negative aspects which is a fairly important issue for people wanting to move elsewhere. Also I specialize in hotel management and urban tourism and Africa is more of a ecotourism destination.
I think Africa desperately needs something like Dubai to make a mark in the tourism world. In Europe you have all the big capitals like Paris and London. In Asia you have Tokyo and Shangai and Hong Kong. America has New York and Sao Paulo and Buenos Aires. And the arab countriest have Dubai. I dont know, maybe im wrong, but i cannot think any african city that has that kind of status. Who knows, maybe the next boom will happen somewhere in Africa. It does not take a lot of time really, just look how fast Dubai grew in like a decade or less, very impresive.
I read a lot about what is going on in the world, i like to be informed. Recently i read about this tiny country in the west coast of Africa called Equatorial Guinea and it has big oil deposits, kind of like U.A.E. Maybe that is the place where there could be a boom in urban tourism, but i have read that the goverment is super corrupt and it is practically a dictatorship, so what im saying probably will never happen.
In south Africa there is Cape Town which is a very cosmopolitan tourist destination. Ironically, before it was destroyed by US and NATO bombing, the same could be said of Tripoi in Libya.
Personally, I would never say that I would never consider Angola. It is an emerging market thanks to oil and diamond industries and as an Educator most likely I would have no problem finding work as English language has expanded into primary schools and is becoming a favored language among the youth. The problem is the party elite hoarding wealth and the potential for civil war thanks to the rebels in Cabinda.
