i don't know if you have had any advice about this yet but with you having small children, like us, you would be better to go around march/ april because it is warm, but just like summer here, then you and kids can adjust to life there before having to adjust to weather at same time. whenever i go on hols with kids to cyprus i always go just before it gets warm or just as its dropping off. all your friends will say 'are you sure its a good idea?' but what they really mean is they are not brave enough to try it!
