Money:

Please contact your bank and let them know you will be traveling in Brazil and may be using both debit and credit cards. If your bank doesn't know, they may block access to your card while you are here. On this note, there's no need to bring large quantities of cash. There are plenty of ATMs and we will make stops for you to take out money. We suggest that each traveler allocates $100-200 for the entire trip.  

The currency in Brazil is the Real (abbreviated to R$). Dollars and traveler's checks can be easily changed in hotels, authorized banks and travel agencies. 

Tipping: 

The service charge of 10% is included in the bills in most restaurants and bars. Therefore, additional tips are optional and are usually between 10% and 15% of the bill. For tour guides and drivers, tips are recommended at the client's discretion.
