I’m a little worried I’ll get bored in Milos. My husband likes to stay in one place, but I like exploring. We would have split our time more evenly but we want to stay on the caldera and it’s just too expensive to stay any longer than two or three nights. Alternatively, we could stay in Santorini for longer but move to a cheaper hotel. Perhaps Santorini 6 nights and Milos 6 nights?
