Estrella de Oro is nearly the, er, gold standard on Mexico - Acapulco, and takes ~5:00. Their website, in Castilian Spanish, works fairly well for
most pages. It also gives tollfree numbers to call to book tickets.
They also offer Servicio Diamante is $610 MXN (this part of the website is absolute crap). All out of Taxqueña / C. Sur, and they also serve Zihuatanejo, Ixtapa (and Cuernavaca, Taxco, Chilpancingo, capital of the state of Guerrero, in which Acapulco is situated, as well). Even an MEX airport - Acapulco bus!
As well, they connect Veracruz / Córdoba (as well as Xalapa separately) in Veracruz as well as Oaxaca city to Acapulco via Chilpancingo (bypassing Mexico City).
Check
this page for hours and tariffs for Diamante and Pluss.
They have regularly scheduled MEX-ACA services: $599 Lujo / Diamante (USD $44.50 currently) and $445 Ejecutivo / Pluss (USD $33.50 currently). Primera is only used on minor such as Cuernavaca - Taxco, and Económico (nope, not at all chicken bus!) on some coastal runs.
Their classes of service can be viewed
here.
As an example of a better Mexican bus line, the
Estrella de Oro classes signify:
Económico / Economy: ~ 50-55 iirc seats in 2 x 2 seating, air conditioning, used on west coast routes. Think "coach".
Primera / First: 42 2 x 2 seats with partial recline (think airplane), air conditioning, restroom, video (not individual screens) and more space than Economy.
Pluss / Plus: 36 seats with more recline, legrests, air conditioning, men and women lavs, video, boarding beverage of your choice.
Diamante / Diamond: 24 seats with extensive recline ("bed type") and leg rests, air conditioning, men and women separate lavs, individual touchscreen video, electric connections, isolated cabin (from driver compartment) and light meal.
I'd not hesitate to take Diamante (though Pluss takes the same length of time, as they are expresses,) and enjoy the greater comfort (and avoid the common video screens with loud shoot-em-up videos).
Getting to Taxqueña is easy via taxi or the Metro (called "Tasqueña" on the metro map).

Go to the Tasqueña terminal on the south side, look at all the different lines and find the best deal, service and time for Acapulco. Bueno.
