The Horizon Restaurant did Greek Nights and also a Latin (salsa etc, not flamenco night) which was great, but that might change this year if they dont get booked. Some of the accommodations might have a quiz night by their bar. The Thassala did jazz nights which were good, the singer was brilliant. The usual TV (sky stuff), last year at the Malibu bar there was a Frank Sinatra singer (came from Hastings) and he was very good, sometimes there is a magic show which some have enjoyed. But there are only two bars so there isnt a lot going on which is why a lot of people keep going back. You might not want that sort of thing every night but for a change there is something if you want it.
Whatever you choose you will have a great time, it is a very special place and great for any age. We went for a walk up to the Kaloudis, (we have stayed at the Galini and the Bardis Studios.the Galini much better for kids I think but further from the sea) its the far end of the sea front before the cliff walk and it is a nice looking place with apartments in blocks, nice pool fenced off for safety and lovely bar area. Shop too... two mins to the beach in a quiet part of the resort as it doesnt get much traffic (dead end).
Have fun... I am so envious of everyone at the moment booking holidays. We dont know what we are doing yet with moving, decorating, kids coming back and forwards. Perhaps I should just do it and let everything else fall into place.
