There is no need to rent a car unless you have specific plans in Acapulco. Bus services run within the city until 11 pm. Most blue and white buses with “Costera” printed on the side are not air conditioned and can be very hot and crowded. Fare is 4.5 pesos.
Beige and yellow air conditioned buses are harder to find and cost 5.5 pesos. Quite often, the air conditioning is broken which makes the ride very hot and uncomfortable.
Acapulco is a bustling city which is easily navigable with lots of transportation options. You will no doubt enjoy the amazing nightlife, the beaches and everything else that this beautiful city has to offer.
