hauteboy, am I missing something about your post? You flew to Accra on a "transit" from LHR? Why?
Over the years, I've had the good fortune to travel to a lot of places - there are places I'd love to go back to, some places I wouldn't mind seeing again, a fair number that I'm indifferent to - and some I would never, ever go to again under any circumstances, Accra being one of them.
Admittedly, I was there in 1977 - maybe it's better now. In those days, you walked across the tarmac to a large, open-on-one-side shed, where the luggage was piled on the ground. Within half an hour of arriving, I was in a backroom, negotiating with an immigration officer (t-shirt, jeans, sneakers, cigarette hanging out of his mouth) about the validity of one of my vaccinations.
In many ways, I think everyone should go somewhere like Accra at least once in their life - it gives you a much greater appreciation for a lot of the things we otherwise simply take for granted. That said though, I'm still mystified as to why you went there....
