To your question of too many places/hotels, etc. To my eye, your not doing the type of itinerary that draws quick comment in these parts. The ones that are 6 cities in 10 days types of trips. We could all quibble a little more time here or a little less time there but you are (with the exception of Siena) staying at each place enough time that you should be able to slow down and enjoy the place of things. Relative to Ischia, I'd be tempted to make a day trip of it over shifting over and splitting your time.
