Yes, there's a bus station close to the beach

Skála is a nice and busy resort with restaurants to do to or little bars. Nice to walk around and also depends on the time of the year you go for example July August is quite busy.

Yes cash machines in the town can be easy to find

We visited Skala beach 5 years ago from our stay in Lassi. The beach was awful, pebbly, rough and you were up to your neck in water within 3 feet of going in. Absolutely no good for small kids. Hated it, Lassi beach far superior with golden flat sand, and beautiful crystal clear shallow sea. No comparison to Skala beach. Although we may have just ended up on the 'bad bit'., not sure.

the main part of Skala is flat outskirts are hilly

Hi, Have in mind that the island is huge and I believe that the capital is where the lively parties and strong clubbing takes place.That doesn't mean that Skala has no entertainment,you'll certainly find quite a few like Captain's Bar,Akri seaside bar,Veto Bar,Metaxa Beach Bar,Yuca Bar etc.Kefalonia is generally more 'laid back' than Zakynthos for example where there is an incredibly strong nightlife which young people adore.But that doesn't mean your daughters won't find something to their taste.

Not sure.

No, no problem

yes right down on the far left close to rocks .past the green paradise and past the sunrise taverna .only I do not think it is an official nudist area .
