www.gohop.ie is the first place to look. I see they have 2 weeks in Zakynthos from Dublin 28th July for €318,,, fab price. Lovely island and you can get ferry to others, ie. Kefelonia (Capt. Corelli's mandolin location).
I see that it is Panorama.ie are doing this holiday. You can leave from Dublin on 28th and Cork on 29th, and it is €600.60 total for 2 persons.
I would love to be there.
Also try www.sunway.ie & holidays direct. There's a whole plethora of websites. Deals are hard to come by this year as the weather here is so crap & everybody seems to be trying to find something last minute..
Good luck with your search
