Make sure you have your passport, credit cards, money, tickets and other important documents handy and secure to take a trip around the world.
Wear your money belt (or another security accessory) and use it to keep your passport and money safe. Organize tickets, other documents and reading materials in your carry-on bag.
Have tickets easily accessible so that you don't have to dig through your bag. Make sure that certain other items are easily accessible for airport security checkpoints.
Get plenty of sleep, eat healthy food and take needed medications on time before you travel. Avoid over-eating, eating a lot of sweets or drinking too much alcohol before you take a trip around the world. Drink plenty of water. Know that jet lag is minimized by making healthy food and drink choices.
Dress appropriately for your first destination. Wear layers so that you can easily make yourself cooler or warmer as needed.
Be ready early for your ride to the airport to take a trip around the world. Last minute things always come up. Shoot for arriving at the airport two hours before your flight.
Prepare while on your flight for the next destination. Review maps. Make a list of what you will need to do just as soon as you arrive such as checking in for your car rental or calling the hostel. Do this for each new destination.
Realize you will feel disoriented each time you arrive in a new place, and a list will not only help you when you get there, but also it will help you think things through before you land.
Drink water on the plane and avoid alcohol. Booze dehydrates people, especially up in the air, and adds to jet lag. Remember to eat either on the plane or when you land. You will need food to think and figure out where you are going next.
