I'll have to explore more. My initial thought was that we would be more likely to get good views of the coastline on a boat (less likely to get trapped on the wrong side of the bus). But we're just starting exploring what to do. I've been looking at this dive trip for a year, and finally booked the trip. I had assumed that I would be diving most days - so the land activities were up to my spouse and daughter to research (and they've done nothing so far).
Fortunately/unfortunately - after booking the trip - the dive operator notified the group I booked though that it only operates on Fri-Sun, which means that I'll have a lot more free time. I'm not sure that's a bad thing. The water is pretty chilly in March - and it's been a long time since I did cold-water diving. I'd love to see more - but as long as I can get two days in I won't be terribly cranky with PADI (the dive travel group which screwed up).
And I'm in the middle of an art history class - we're just about to get to the art era that is preserved in this location. So that's a nice coincidence. And despite the discouraging words we got from a friend who lived a good part of her life in Italy about the Naples area, it looks like there is far more to do than we can accomplish in 6 days. I'm also in a drawing class - and Amalfi/the Amalfi coast looks fantastic for a lot of sketchs. And I'm pursuing a BFA in photography . . . so a perfect location, even if I only get to dive for a day or two.
