Important Things to Concider

1. When ever you go away from your hotel,
EACH OF YOU SHOULD ALWAYS MAKE SURE TO GRAP A BUSINESS CARD FROM THE FRONT DESK THAT HAS THE HOTEL NAME AND ADDRESS ON IT. DO THIS REGARDLESS IF YOU ARE GOING OUT ON YOUR OWN OR WITH THE GROUP.
With this information you will always to able to get back to your hotel with no problems.
2. Do not leave any cash in your rooms when you leave. Each of you should keep a little cash in different areas on your person. Each of you should also have a credit card.
3. You should have two credit cards (Different accounts)
4. Always make sure that you have your passport on your body whenever you leave your hotel rooms.Do not leave them in your rooms, not even just to go eat.
5. Be sure and have your Trip Insurance information with your other travel documents on your person when traveling. Hopefully you will not need them, but if you do you will have no worries. If you face any problems, Illness, missed flight, lost luggage there is contact numbers for you to call. Do this right away!
6. If you want to purchase souvenirs during your trip I would try to use your credit card as much as possible. That way you have proof of purchase, and tracking if a problem arises.
