Bus travel Info-Puerto Vallarta

If anybody is looking at going to PV from Zihua/Ixtapa,I went to check for my return trip yesterday as I will be heading back to PV next Monday and the rate for a direct service in first class is 830 pesos($70-75). It's a 14 hours ride and it leaves at 20:40 so you go through the night and you get in PV around 11:00 in the morning...
