1. Look up the monetary conversion before you plan your trip. Finding out that Rs 75 is equal to just 1 euro is a bad surprise. Make sure you do your math before you pick up your destination to get a sense of what the conversion rate is.
2. Keep copies of your passport. If your passport gets stolen or lost you want to be sure that you can still get back into the country, or be able to prove your citizenship.
3. Register with your embassy. If there is a problem, this will make it easier for your government to contact you and get you to safety.
4. Make sure your ATM card works in the country you are visiting. European banks have switched almost completely to the more secure chip-and-PIN technology, and fewer businesses abroad are accepting the outdated cards.
5. Always have local cash. Not every place takes credit or debit cards. Otherwise, you may find yourself on a spot when travelling in trains or buses.
6. Having an idea about the local cuisine would be beneficial for you if you are a foodie.
7. Research on sight-seeing places and other activities. When it comes to recreational activities, global numbers indicate that majority of Indian travelers prefer outdoor activities.
8. Set up your cell phone to avoid international data roaming. Many business travelers have an international calling and data plan. But infrequent travelers don't. The biggest costs can come from transmitting data overseas.
