We took the 'shuttle boat' transfer altho' more expensive than the local transport, it's regular and convenient. We explored the back streets of the Rialto district, the food market is spectacular, Cantina Del Mori is one of the oldest tiny bars in Venice and enjoyed a glass of wine & nibbles at 11.30am ! (I know)...and then lunch at The Bancogiro which is a fabulous bistro with outside tables and reasonably priced. Venice is a must do!
Montenegro is stunning, Kotor is a 'small' Dubrovnik with even more dramatic scenery. We wasted time with a mountain tour on a 25 hairpin bend road & a mediocre stop at a 'ham smokehouse' - wouldn't recommend this as Kotor has plenty to offer for the day with beautiful shops, cafes & restaurants.
We docked in Catania & took the excursion to Taormina which has to be one of the most beautiful little towns in Italy/Scicily. Very upmarket, individual boutiques, lots of local oil, honey, wine, salt - great gifts. Fantastic cafes. Views of Mt. Etna. Truly spectacular.
It was very hot in Valletta and it's quite a walk from the port so we hopped on a 'horse & cart' which was pricey at 60 Euros but it's an hour long tour with an interesting commentary from our driver and meant we saw more of Valletta than we would have done on foot. The shops are a tad 'British' with Marks & Spencers etc...but overall it's a lovely port - next time tho' we'll take the excursion to Medina.
Our 2nd time in Naples, and we've 'done' Sorrento on a previous holiday so had planned to do Pompeii but cancelled due to the heat (93)...so we walked off the ship and in 5 minutes found the 'upmarket' shopping area in Naples, enjoyed coffee, cake and wandering around.
