Bus Transpotation

Any help with bus schedules between PV and Mazatlan.

Names of companies members have had good success with and names of companies you would never ride with again, would be helpfull.

Thanking the members of this board for any responses.

The Pacifico line goes to Mazatlan via Tepic. Twice a day 12:15 and 10:45 pm. 254 pesos, take a blanket - the AC is fierce.
