We are 61 yr. old couple from Florida and also going on the Ruby Princess Aug. 28, 2013. We booked only one shore excursion in Katacolon. The ships shore excursions are very expensive. We think we will explore most of the ports on our own, except Naples. We may want to get together with other couples to take a small group tour. Any ideas for Naples? We have been checking tour reviews, etc.
