Got to rate Skiathos as my fave as married there( i know), great little island although getting cosmopoliton and hence price rises..Some very quiet resorts and great beaches such as Troulos and Koukanarious.How would you rate Crete, Corfu, Zakinthos and Skiathos against each other?
Crete is fantastic too, recently stayed in Koutafalari and old Hersonisis...very traditional greek , but not on the coast,approx 30 mins on foot..10 by car.
Was in Corfu in August in a tiny resort called Aghious Georgious North.
Fantastic family run hotel called Costas Golden Beach..Hotel is right on a huge beach..lots of beach bars/ restaraunts.
Been there 3 times, absolutley immaculate, and the lad in the bar married a lass from Silky, so gets over for games and hates the mags..
Currently in Zante, small resort called Vasilikas, lovely beach but very quiet compared with Argassi along the road (5/6km), like bloody Backpool.
But all in all, prices remain prety constant around the islands...15-18€ for main course, 5€ for a large beer, 7-9 € for a martini type drink and 10-12€ for a cocktail.
Hope this helps.
