The Camino Real Acapulco Diamante is a small gem tucked away in a private neighborhood of the Diamond coast (Puerto Marquez). Because it is not located near the main Acapulco Bay, it is a bit more pricey to get out and about. But, the good thing is that the hotel has their own taxi cabs and they second as tour guides, too.
If you take a cab and they offer you tour services, take it! It is well worth the money you spend. We paid about 600 pesos (= approx $60 USD) for having the taxi driver take you around for a day.
The staff at the hotel are very friendly.
