First, use the same precautions you use when you are home.
Dont walk the streets alone at night.
Dont flash jewelry and money.
Do not tell anyone you are there alone.
Do not tell anyone where you are staying, and how long you are staying.
Don't give out your number (unless you wanna) just know they will bug the hell outta ya! Lol!
Use red plate taxis negotiate pricing BEFORE riding. Same with tours negotiate price beforehand.
Dont let folks walking the beach put a bracelet on your wrist its hell giving it back if you don't want it..
If you are offered some things your not interested in a polite but Firm "No Thanks" usually works.
Other then that Enjoy!
