Cash is king
Where Cash is King is one of the Things About Ecuador You Should Know. In Ecuador, it is usually preferable to have cash in your wallet rather than relying on your credit card. Sure, you'll be able to pay with a credit card if you stay in a fancier hotel, but you'll need cash elsewhere, such as at local stores, bus stops, and even most travel agencies. People always had what they required for the day in their wallets and left the rest of the money in the hotel room because international passengers attract pickpockets. It's also a good idea to plan ahead and find out if your next destination has an ATM.
The issue begins at the ATM. You get all twenties except one ten and two fives when you input your debit card for $100 or $200 withdrawals. Now try to find a local vendor or hail a taxi and pay them twenty dollars for their services. As their mind rushes over how to fix the dilemma without losing the purchase or fare, they have a look of almost fear on their face.
