transportation to Manzanillo questions

We have taken many bus trips all over this country, on all classes of buses.

Whenever the option for a First Class (or higher) is available, that's the way to go. If you are going on a scenic route and have a choice, go during the day. It is quite beautiful going north up the coast from here, we recommend the bus, during the day, the highest class you can get. You will have a great ride.

Like stated above, go to the bus station, read the boards. Questions? Do your best and smile, you'll get the information you need. Be Brave!!

Excellent reply!

I would add to also be FLEXIBLE. You can often shave trip time by changing buslines, though sometimes that means going to a different bus station or awaiting a bus on the side of the road (only Estrella de Oro has a separate station from the rest of the buslines here in Guerrero, I'm unaware of other buslines that do this anywhere else).
