Any advice regarding this island? Holidays in September are coming up really cheap and I was wondering why?

My advice GO, it is a fantastic island for a holiday in greece, very laid back and scenic.

The prices will be cheaper as it is getting to the end of the season and you will find that some places will have closed for the Winter however you will still have some lovely little tavernas open, the weather might be slightly more mixed and not just as warm but still pleasent.
