Grocery stores are the best tourist resource. Cheap food, local flavors. Find the nearest hotel and save a ton of money. Every day, eat outside.
Learn to swim. You never know when you may need to use this skill.
Wash clothes in the sink or shower. Use hotel soap. Or bring a bottle of washing powder with you. This is much easier than finding a washing machine in a foreign country.
Always carry a printed map of the city you are about to visit with you. You never know when your phone may break or you will not have a connection.
Make sure your bank cards work.
Register at the doctor and insurer. Double check and make sure you have all the appropriate vaccinations. You should also find out if an overseas insurance policy is applied in an emergency. If not, then consider additional insurance.
Copy of passport. If your passport is stolen or lost, you must be sure that you can still return to the country or confirm your citizenship. Leave a copy of your passport at home or with a trustee. Consider creating an electronic copy, which you can also save in your email account.
Register at your embassy. If there is a problem in the country you visited, it will be easier for the government to contact you and provide additional security.
Check the currency conversion before departure.
Go to a bank or ATM in the country you are visiting. The costs at or near the airport are usually huge.
Buy tickets in advance to the places you want to visit or see.
Download the appropriate application before traveling. Avoid charging an operator to download the app while traveling.
Check for events that occur during your stay. This will help you not to miss the best events taking place in the city, such as festivals, holidays and outdoor events.
It is also worth trying local dishes. You don’t want to leave the country without tasting local delicacies.
Learn how to say "no, thanks". In most guides you will learn how to say “yes, please,” “thank you,” and “do you speak English?” But in some countries you really want to say, “No, thanks.” Think of crowded markets in Asia. Knowing how to say “no, thank you” in their language will make your trip calmer.
