Read up on the country you're visiting before you go there.

Avoid the "if I shout louder in English they'll understand what I want" school of communication. Even making the effort to learn a few phrases of the local language will change your holiday experience. In countries where haggling is standard practice, it may even save you money, as traders are more likely to reckon you've a handle on local prices.

Expand your culinary horizons by eating and drinking what the locals like. If you've got a bit of the lingo, interpreting the menus will be easy, and even if your dish isn't quite what you hoped for, the surprise might delight you.

Use public transport.

Try to dress appropriately. Exposing your new tan to public view can cause offence in certain places, so be sensitive to local culture.
