Will I have any problem exchanging my money or paying in dollars?
No, the US dollar is the most accepted foreign currency in Durango; many hotels, restaurants and shopping malls take them with no inconvenience whatsoever; nevertheless, it is possible that you may get a lower exchange rate than that at an exchange or bank office. The rate is determined by the market and it may vary a few points from one day to another; it is also possible to exchange euros.
It is not advisable to go to the black market; although the rates are higher than those at the exchange offices, you take the chance of getting counterfeits.

Will my credit cards be accepted?
Yes, especially in businesses related to the tourist industry, such as travel agencies, hotels, airlines, car rentals and restaurants. They are also taken in shopping malls and in large shops in general. This situation changes in the towns and communities far from the city, where their use is more restricted; hence, it is recommendable to carry local currency.
The most accepted credit cards are Visa, MasterCard, Diners Club and American Express, and the establishments taking them usually have a sign on the door or in any other visible place; in any case, and in order to avoid misunderstandings and unpleasant situations, ask before consuming.

Is it recommendable to bring traveller checks?
Yes, because they constitute an easy and safe means of getting cash; it is possible to cash them in at the bank offices of Durango; usually only between 9:00 hours and 13:00 hours.
It is recommendable to have the checks issued by known and prestigious financial institutions and preferable for large amounts of money.

How much should I tip?
Although it is not mandatory to give tips, it is usual to leave between 10 and 15 percent of the bill depending on the quality of the service.
