Make sure you're healthy before you start travelling. If you're embarking on a long trip, If you wear glasses or contact lenses take a spare pair and your prescription.
If you require a particular medication take an adequate supply, as it may not be available locally. Take the prescription or, better still, part of the packaging showing the generic rather than the brand name (which may not be locally available), as it will make getting replacements easier. It's wise to have a legible prescription or a letter from your doctor with you to prove that you legally use the medication to avoid any problems.
No matter where you are headed or for how long, there are a few travel essentials you must take. And not all of them have to fit into your bags; some must fit into your head. We will start with the latter.
General Don't take anything you would feel terrible about losing! I.e., jewellery, watches, laptops, etc. If you can't replace it, leave it at home.
Always be certain of the price before you request a service or order something in a restaurant.
Don't forget your manners. Learn to appreciate the things.
Learn a little bit of the language of the place(s) you are visiting, or at least some courtesy phrases.
No matter where you are, don't fight the local customs. Enjoy them. If you are unsure of what to do or how to do it, simply observe the actions of others.
Don't ever insult a culture or country or brag about how your way of life is superior to others. If you do, you will be amazed at how soon you will be alone.
As far as material things go, remember and repeat these words: PACK LIGHT.
A good rule of thumb is to pack half of what you need, then take half of that out of the bag. Recommend a medium-sized backpack . Measure the weight before you go walking up a steep hill. Remember, you can do laundry in other areas just as you can do so at home.What goes into that backpack or suitcase is essential. We will skip the fashion recommendations and go with the basics. Before leaving, be sure you have the following:
Passport Also, make a laminated copy and keep in a separate place. It makes it much easier to replace if lost or stolen. Don't forget your plane/train or other transportation tickets.
Travel or sample-size toothpaste, toiletries and other bathroom-type essentials.
Credit and ATM cards Visa are welcome almost anywhere and ATMs have become the best source for cash worldwide. Before departing, call your bank to be sure there are ATM locations in the area(s) you are visiting. It's not a problem in most major cities.
A comfortable pair of walking shoes and/or sandals.
Loads of film or carry a big memory stick We also like the pocket cameras and the small digital cameras. They take excellent quality photos, don't take up much room and are small enough to carry with you at night for those endearing "happy snaps."
Take any pills or medicine you may require.
Terrorism/Safety It's best to be prepared, cautious and to avoid any potential hotspots. Stay alert to conditions and check newspapers regularly to stay on top of any major worldwide threats or events.
