Safety
The crime-wave that struck Acapulco in 2006 passed and things have calmed considerably, though you may still read reports that Acapulco has a high crime rate. Much of Mexico is experiencing increased rates of crimes, crimes directly related to the trafficking of illegal drugs en-route to the United States. At the current time, the rate of serious drug-related crime in Acapulco appears to be less than what's being experienced in many other parts of the country.
More often than not the types of crimes that do take place are crimes of opportunity, mostly petty crimes of theft. Safeguard your belongings when you're at the beach - don't leave things unattended as you enter the pool or swim in the bay - and don't flash too much expensive jewelry when you walk about and you should be just fine.
The security issue in Mexico, including Acapulco, is affected by the general distrust of law enforcement officials. Police are, generally, considered untrustworthy. If you're victimized, however, do report the crime to the police and the local consulate of your home country (or your Embassy in Mexico City via email).
For the most part, Acapulco is an enjoyable and safe destination city. Remain aware of your surroundings and the people around you (advice that is good no matter one's travel destinations), and you should have an enjoyable visit.
Health
The climate in Acapulco is typically hot and humid, so check with your local physician concerning any precautions you should take during your visit. Bring good sunscreen with you, and your favorite brand of tanning lotion. Be cautious when patronizing street and beach vendors selling food because some of the items may not have been property stored, refrigerated, prepared or cleaned. It's best to drink bottled, purified water and drink ice cubes made from purified water. Take some precaution to protect yourself from mosquitoes as Dengue Fever is a concern along the part of the Pacific Coast of Mexico where Acapulco is situated. When we are on vacation we sometimes leave 'common sense' back home; bring it with you and exercise it and you should be just fine.
