Our ship will be in Naples for 11 1/2 hours. Celebrity's shore excursion lists "Capri On Your Own" as 9 hours. The description says 50 minutes each way and 5 hours on Capri, which adds up to 6 Hours 40 minutes. Anyone done this excursion? We want to have some time in Naples. A 9 hour tour would pretty much knock that out, but, if it's really closer to 7 hours, Naples would be doable.
