I'm going to Aghios Gorgios, I've been there an embarassing number of times (I think it's 9, or maybe 10), but the kids absolutely adore it and don't want to go anywhere else. My parents go there several times a year and we always stay in the same place, eat in the same place, have the same routine each day etc.
Mr Mika Mad can't stand it because it's so boring and repetitive, so he's not even coming with us this year, which is why we're going to Holland as well.
