Driving in Luanda it's an art. Even if you are the best driver in the world, you will have a lot to learn here. So don't hire a car, try to get a car with a driver. Luanda it's...Luanda. Everything that you think that can't be done when driving a car or a motobyke, you will see it in Luanda. There's no updated GPS router for Luanda streets, there's to may drivers, some times you can't find the street name and when you think that a police man is there to help you out....think twice, ok?
Unique Suggestions: Get a local driver. Do it contacting your hotel or your friends before you get to Luanda.
Fun Alternatives: Better than hire a car and contract a driver, it's to have a friend with both!
Further to the previous warning on customs, I think they mean the "Policia Fiscal". These officials have a small office in the international departure lounge, on the ground floor. They will stop affluent- looking europeans and americans and usher them into a small interview room.
The Policia Fiscal are there to ensure you do not take the local currency ( Kwanza) out of the country. They are very polite and they might want to see in your luggage. If you do not have Kwanza they will ask you if you have US dollars because of course they would like you to offer them some. Do not give them any. I have been ushered into this room several times and I have found these people to be quiet, well mannered and unthreatening.
Unique Suggestions: Just be as polite as they are, they are only doing a job.
Do not leave the country with money in your pockets. When you go through customs they ask if you have any money and search for it in you clothes and bags. Spend it all before leaving the country, give it to someone you met there...better than leaving it at customs.
