That's cool! Ghana will definitely be good for you if you're looking for a boost in creativity. I just returned home from there a week ago. In the 4 trips I've made to Ghana I've found the creative juices flowing each and every time. The culture and people are awesome and grow on you more and more. Finding your way around at first is not easy, but will become easier as you get to know where things you need are located.
How long will you be visiting? Did you get an apartment or will you be staying in hotels? Some of the places I've been to are Cape Coast Castle, Kakum National Park Canopy Walk, Aburi Botanical Gardens, Legon Botanical Gardens, Till's Beach Hotel, Anamobo Beach Resort, Big Milly's Backyard Kokrobite, Labadi Beach and Tawala Beach in Accra.
I urge you to take trotro's to some of the places you travel to. They are inexpensive and give you an insight into daily life in Ghana. The more places you travel around to the more you will learn about the culture.
Akwaaba to Ghana and happy travels.
