I am looking to book at ferry from Naples to Stromboli in July. We are considering the 5pm crossing, arriving at 10pm - as I thought it might take in some good nighttime views of the volcano on our trip in. Originall had planned arriving earlier in the day. I just thought arriving late might give us an added bonus of a night time view from the ferry rather than booking a separate boat trip. Is that actually feasible or sensible ?
