We are 4 Aussie ladies travelling in Sicily in Oct 2014. We want to catch a bus from Agrigento to Palermo on the afternoon of Sunday 19 Oct around 4.30pm and I need to know if we should / can book our seats. I'm guessing that this would be a pretty popular bus and we don't want to miss out. One bus line is Cuffaro but their website has no provision to book or pay for tickets. We are staying at Hotel Porta Felice in Palermo and hope that the bus can drop us not too far from there as we will have lots of luggage (Palermo is our last stop before we head home via London). Any advice / suggestions would be appreciated.
