This is a question you need to ask directly to Greyhound by calling them. Or you can go online to their website and research the price there. This forum is more for questiins about the actual bus station that people who have been to the bus station can answer. For ex:Do they sell snacks? Btw: yes.
Book ahead is a good decision
They have different options you have to call or go online.
