I am staying in Santorini for 7 nights in August for my honeymoon and am thinking of making a day trip to Ios. I would arrive around 12:30 and the ferry back to Santorini is around 18:50.
What would you do for these 6 hours? I realize I won't be able to do much, but just to taste another island for the day would be fun without having to pack/unpack, etc.
I've heard it's a big party island with college kids, but I think by the time I leave, that would not be an issue.
