Usually from May to August is the red tide season (murk waters). But, definitely it would have to be at the boca chica hotel, there are corals with tropical fish io that area and there's a restaurant for drinks. Check out their web page:

The must see places would have to be, hmmm, ok here goes:

1.- Cliff divers
2.- Chapel of las Brisas
3.- Hotel Casablanca
4.- Fort of San Diego
5.- House of Diego Rivera
6.- Sunset at Pie de la Cuesta
7.- Mirador of Puerto Marques (look out point)
8.- Cathedral of el Zocalo
9.- Drinks at Sr. Frogs
10.- Shotover Jet boat ride
11.- Glass bottom boat ride at Caleta
12.- Swim with the dolphins
13.- Oceanriders boat ride

I am probably leaving out a place or two, but these would be the most representative of Acapulco. There is no particular order, I enjoyed the most the dolphins.
