Take your own from home its a little cheaper and take lots, make sure that you get some with insect repelant as you will be eaten alive. we ran out and could not find any with repelant, and got bitten. Also take insect spray repelant for when you are walking out in the evening. You never see the buggers and they will get you.
Sorry didn't mean to worry you but if you take precautions then you won't have a problem.
They tell me that if you drink ouzo then they don't like it so get stuck in.
Have a good holiday I wish I was coming back with you . We were there in May and June You lucky thing.
