Wonderful trip! I strongly recommend several of the Optional Experiences to make the most of your time, including the sunset boat trip in Paris (you see the Eiffel Tower aglow!), walking tour of Hidden Venice, and walking tour of the Colosseum in Rome.
Be prepared to walk a lot (I hit 10-14k steps most days!) Be prepared for early mornings.
Marvel at Gaudi’s masterpieces in Barcelona, spot locals sipping pastis in Nice and admire Florence the home of Michelangelo and the Renaissance, as you circle the azure waters of the Mediterranean. Embrace the city of Pisa with a stop at the famous leaning tower, where Italian astronomer Galileo was said to have pioneered his theories of gravity. In France, work up an appetite in the medieval streets. In Spain, dine with the locals in Basque tradition with an evening of San Sebastian pintxos tastings, snack-sized tapas, while sipping on a refreshing glass of local Txakoli wine. In Rome, taste the seasonal flavours and of course, handmade pasta.
Good introductory cross-section in major cities. Good balance of scheduled vs. free time. Would like a little more emphasis on art--especially Uffizi Gallery and Pisan Camposanto--plus entry into St. Mark's/Doge's Palace and Duomo church (rather than some of the shopping stuff). A little too much commercial, too little history/art. (Some of guides under-informed, including one who said Galileo discovered the "two planets" around Jupiter!).
