hi, we have been to skopelos at least 12x and love the place there are 2 really good websites skopelosweb and skopelos.net both give really good info. i have not stayed at nina but looking to go there next sept you should find getting to alonissos very easy with lots of ferrys and hydrofoils going back and forward all day also a glass bottom boat form skopelos town to alonissos and the marine park. if you want to know anything else just ask .kev
