Thanks to the advice found here, the private port tours I booked for my group of 22 while on Carnival Liberty Med Cruise were the highlights of the trip! I booked with Monia & Daniele Melaragno at
www.driverinrome.com for tours from Naples, Messina,and Livorno; Marie at
www.sunnydays.fr in Cannes and Jernej at DubrovnikPremiumServices.com in Dubrovonik. They were all prompt and very professional. Besides being well-educated, the guides were young and enthusiastic about sharing their love for their country and culture. Most importantly, they became our friends for the day and we left with found memories of what we saw and heard because of them. The icing on the cake was that the private tours costs were at a great savings compared to those offered by Carnival. We set our own pace and picked our own itineraries. Thanks to all who gave the recommendations.
