Here I am!! Am I too late? Bugger, I'm forever late.
Okay, Accra for your hols. All friends who have come have enjoyed their stay and wanted to come again. It is a wonderful country full of hospitable, laidback people, it's very safe (except the driving!), and quite relaxing.
But... this is not the place for a classic beach holiday. It will be, as CM put it, very basic. There is little tourist infrastructure and no service culture at all. The sea off Ghana is very dangerous for swimming - don't do it. (With one exception, and we can come to that later if you like.) The place is pretty deforested, you will not see any 'game' unless you trek up to Mole, and even then it's not a given. Also a decent hotel, with a/c and relatively reliable running water, can be quite expensive.
Ghana is, however, a wonderful introduction to Africa if you and the DCs have not been. It will be a sort of 'discover the world' kind of holiday. The slave forts are incredibly powerful places, the markets are good fun, the local food is pretty good (heavy and oily and spicy, and yummy). There's plenty to keep you busy for a couple weeks. It's a good place to travel with children.
Hey, tell me what you want. I can do a whole itinerary.
