Is it recommendable to bring traveller checks?
Yes, in some cases traveller checks are safer than cash; they can be easily cashed-in in any bank office, mostly if they have been issued by a well-known and prestigious firm. Besides, they are easily replaceable in case of loss or theft.
How much should I tip?
It is not mandatory to tip; however, it is usual to leave the equivalent of 15 percent of the bill at bars and restaurants in Zacatecas. Bellboys, luggage porters, parking valets and gas dispatchers can be tipped with a dollar.
