Read Up On local Culture
Years ago this meant buying a book on the subject. Now we have the Internet. There’s no reason not to learn about the place you intend to visit. If anything it makes you anticipate the holiday more.
Know about local laws.
This tends to be overlooked. People know the drinking age in the USA is 21, but are so used to drinking at home that they automatically go for a drink when traveling. Drug law and dress codes in some lands are incredibly strict. Discussing the government is best avoided in some countries.
Money and Credit Cards
Get a credit card that works with the local ATM is possible. This will massively reduce transaction fees. Keep cash on your person to a minimum. Plan days in advance so you will have sufficient cash for expenses.
Let Others Know Where You Will Be
This can be as simple as sending some regular emails. Leave an itinerary where only trusted friends and family can see it, and update with private email. Do not use social media for information.
Have accommodation arranges, at least for the first night.
You don’t want to spend a significant part of your trip look for a hotel.
The internet is a mixed blessing here. There are scams, but there are also loads or recommendations and reliable sites. Youth Hostels tend to be a reasonable bet.
To Avoid or not Avoid Situations
Meeting locals is recommended. But being swindled is obviously a disaster. There’s no simple advice here, but sticking with crowded areas will lower the risk of assaults, as will avoiding dark alleys. Do some internet research on the dangers of the places you visit. Ask hotel staff for advice.
Taking Day Tours
Day tours tend to be good for getting a lot in, and with transport included you getting a fair amount for the money. Some travellers look down on package tours, claiming we should be independent. But add a tour or two to an independent holiday if it serves your interests. Make sure it is suitable for English speakers.
Putting Too Much Information On Facebook or twitter
It people see you are travelling they might target your home for theft, or they seek out hotel where you are staying. Thieves can get a lot of information from a photo or two. Unless there are people minding your house, keep information confidential. Post photos when you get home.
Showing Valuables in Public
Smart phones and camera are targets for thieves. Unless you have a way to prevent theft, keep them hidden. Keeping valuables in older luggage means they draw less attention.
Get Travel Insurance. It’s not often needed, but essential when it is.
