The Costa Rican national currency is the colon. De biggest note is 20.000 colones (± $40), folowed by 10.000 (± $20), 5000 (± $10), 2000 (± $4) en 1000 (± $2). Besides colones, American Dollars are accepted almost everywhere. Bring small notes ($1, $5, $10 or $20). Euros or English pounds are accepted very uncommonly. You can change them (Banco Nacional, BCR). But it may take quiet a lot of time. A better idea is to leave them at home. It is NOT recommended to change money inside the airport. The exchange rates are much lower than normal. But there are cash dispensers. Cash dispensers: In almost all bigger places it is possible to withdraw money from cash dispensers. Most of the times you’ll get Costa Rican colones, at some banks it is possible to withdraw dollars (BAC San José, for example). Credit card: Paying with credit cards is possible in almost every place. VISA, AMEX and Mastercard are widely accepted. Restaurants: Include 13% taxes and 10% service costs in their prices. Please note that these additional costs are not always included in the prices in the menu: they are charged when paying the bill. Tips: Tips are most of the times included in the bill you pay in restaurants. Extra tipping is always appreciated. Tipping is usual in hotels for maids, bellboys, drivers and guides (in short: people offering service in the tourist sector). Tipping is not usual for people offering service in the non-tourist sector (supermarkets, taxi drivers, public buses). Bargaining for better prices is not a nationwide phenomenon. Please, just limit this behaviour to the souvenir shops. It is very easy to offend a Tico if you try to do it elsewhere!
