So you would enjoy 3 days in a bus doing a tour of central greece , delphes , epidaure , olympia and afterwards a cruise in the greek islands ?
Yes, this sounds interesting :) I suspect people who have never been to Greece would like to do some sightseeing, so, Athens, with The Acropolis and visiting some museums with all those statues, pottery and other ancient stuff :) The theatre at Epidaurus, Delphi, etc. And a cruise afterwards - this sounds nice :)
3 days in a bus doing a tour - that would mean sleeping on the bus? I usually can't sleep on the bus :/ But that's only me ;)
nobody wants to go to Greece anymore
I don't know about other people, but I would :P Never been there yet ;)
as it's overpriced, with filthy sea, strewn with rubbish and full of extremely rude people.
Turkey or Croatia offer a far better all round holiday experience, in my opinion.
I guess there are some ruins from ancient times in Turkey and Croatia, but I'm sure you can get far more and more interesting in Greece, so if someone's interested in sightseeing specifically this kind of stuff, Greece is the place, I guess. If you go somewhere only to relax, to lie on the beach and swim then Turkey and Croatia is probably as good or better, I don't know.
People seem to be pleased with Greece judging by what they write on this forum:
Manu, maybe try to put some of those posts in Polish into Google translator, perhaps in this way you'll get more information than here ;)
