I`'d only have a Week though which isn't even enough time to fully experience one of the cities. I may do one this yr, and the other next yr. In the fall I'm looking at Cairo or a city in Morocco (for next yr, I already have my trips for this yr planned).
Ok yea, if just a week then do one of them.
I'll say this, Accra is like Lagos on training wheels. Very similar culturally but not as hectic. It's good for an English speaking first time visitor to Africa.
For me, I plan to split 8 days between Lagos and Accra. I've been to Lagos many times so I'd just be visiting family and friends. Accra I've also been to and done the touristy things, so less pressure to experience the culture.

Will have to hit up my friends, but attending a Ghanian/Nigerian wedding in a few weeks so they can put me on.
