What practical mistakes do first-time visitors make in Mexico?
The mistakes are usually simple: trying to cover too much, treating safety as one national answer, assuming every transfer will be easy, carrying too little cash margin and relying on English or apps to solve everything.
Answer
Mexico becomes much easier when the basics are handled before the trip gets interesting. Learn enough Spanish for greetings, directions and awkward moments. Carry a sensible mix of payment options. Do not leave airport transfers, late-night transport or long-distance bus choices to the last minute. Check whether the region you are visiting needs a different safety posture from the one you read about elsewhere. Most first-timer problems are not dramatic; they are small bits of friction stacked together until the day feels harder than it needed to be. Plan the dull parts well and the good parts have more room.
