hi Smoosh
we are usually on the midnight special,usually leave Arillas about 1pm in the morning.
so we look at it as another full day in Arillas...Usually crawl out if a taverana pick up the luggage & away.
The hotels nearly always fix you up with changing/washing facilities so I would not worry about going on the beach etc.
We have only been on the Pasxos/Parga trip and we got back to Arillas about 10pm.
the Paxos / Anti paxos should return earlier as iti s not as far on the boat..but personally I would not risk it..If the weather turned nasty you may not get back!!
Just treat it as another days holiday
