Tips for Tourists Visiting Queretaro
Money
Always carry small bills and change. You will find that a lot of places will not be able to change 500 pesos (about $50) or more. So make sure you have bills and coins of 50, 20, 10 and 5 pesos.
Taxis & Transportation
Taxis are an economical choice of transportation. However, you should always ask how much before getting in. You can ask "Cuanto es... (al centro, al mall, al restaurante (restaurant name), etc.) If your Spanish is bad and don't have a Spanish-speaking friend along, get the hotel or restaurant or the establishment you are visiting to call a cab for you.
General Tips
DUCK! If you are close to or over 6 feet tall then duck when you enter through doorways and as you pass store fronts. Many door frames and over hangings tend to be on the low side. If you get distracted then you may end up hitting your head a lot.
