Most banks in larger towns have international ATMs. Credit cards are accepted at most tourist hotels. Bring US dollars or euros.
Although service charges are generally included in the bill, tipping is common in the cities these days due to the large international presence.
Hotels RFr500 per bag is standard.
Restaurants For decent service 5% to 10%.
Guides/drivers US$10 per person per day.
Car parks It's a good idea to tip the men who watch (and sometimes clean) your car. A tip of around RFr1000 is appropriate.
