Most people spend about a hour visiting the Piazza and taking their iconic "hold up the Tower" photos. If you would like to spend more time in Pisa, it is a beautiful town, looking similar to Florence as you stroll the banks of the River Arno. You can also buy timed tickets to climb to the top of the Tower. But a better plan would be visiting the Leaning Tower in the early morning or late afternoon (when cruise ship tours are not there) and plan a day visiting nearby Lucca. If driving, there is a pay-parking lot a block from Piazza dei Miracola.
If you want to visit the Basilica, it's free because it is a functioning Church, but you will have to wait on very long security check lines--often three hours! Bring water in hot months. It's a magnificent--if overly opulent--piece of architecture and the seat of Christianity, but if you are going to pray, you might not find peace here. It is very crowded, noisy and there are signs warning of pickpockets. If you want to visit for religious reasons, do so on Wednesday mornings when the Pope has his Papal Audience and addresses the faithful in the Piazza. There are free tickets for seats that you should obtain well before your trip and then you should arrive 1-3 hours before the Audience. Bring water, sunscreen and perhaps an umbrella--the Piazza can be very hot. Tickets do not guarantee a seat, but there is standing room for 80,000 people in the Piazza.
Don't expect to have a personal experience in the Sistine Chapel where you can sit and ponder the glorious creation of Michelangelo. Years ago, people would lie on the floor with binoculars and spend hours looking at the details. Those days are gone. Large tour groups are hustled in--and out--along with "private" tour groups (we had a private tour). They allow about ten minutes, and most of this is spent sweating, listening to the cackling crowd, with Oriental tourists donning hats, unaware that they should be removed when in a Catholic chapel of worship. And just try to get a seat on one of the side wall marble benches. If you want to savor the Sistine Chapel in both high resolution detail views and in 3-D, click HERE.
The Steps are in a chic shopping district where you might not be able to afford their offerings. There is poet John Keats' home above, an English tearoom nearby, a beautiful Fountain of a Roman Galley below and lots of tourists taking the load off their weary feet. I don't see the attraction.
It's easier to buy your tickets at the entrance up the hill slightly at the entrance to Palatine Hill. The 2-day tickets are good for the Hill, the Forum and the Colosseum. I suggest making your visit to the Colosseum in early morning (stand on line at 8am) or 1-2 hours before they close. Avoid the middle of the day, especially in summer--there is no shade.
One of the best and most interesting times to visit would be in the middle of a rain storm... the rain falls to the marble floor from the 27 foot occulus above making a beautiful sound. High noon would be best to see the sun shine straight down. Beware of pickpockets inside this functioning church! The piazza outside is lively and worth a visit. To avoid crowds, early or late in the day is best.
Stay clear of Rialto and San Marco--that's where most tourists flock. Instead, check out San Giorgio Maggiore, the island just across from San Marco. Enjoy the views looking back at the Campanile. The colorful island of Burano is also worth a visit. Wander the back streets and alleys of Venice to avoid the crowds. Later in the afternoon when the cruise ship groups have gone is much more calm.
Very early in the morning, or late evening is best, otherwise you will have to wait your turn to get close to the edge of the Fontana to ensure your return to Rome by the traditional coin toss.
There are many other amazingly beautiful Tuscan hilltowns worth visiting other than this over-hyped, buss tour destination town. Try Pienza, for instance.
Almost nothing helps avoid the crush of people and the large tour groups. If you book a Private Vatican Museum Tour, talk him into getting you to the Sistine Chapel ASAP, if you want to savor it without throngs of disrespectful tourist groups, otherwise, the rushed tours will eventually swallow you and your "private tour guide" up.
Skip it entirely. Consider that Romeo and Juliette are fictitious characters. No one named Juliette ever lived here, and there is no evidence that Shakespeare ever stepped foot in Italy. Bus tours dump throngs of people off here to pay an entrance fee to a house that has nothing to do with Juliette, and they grab and polish Juliette's bronze boob on the statute below. Teens write love notes and post them on the wall with chewing gum. Get tickets for an opera in Verona's Roman arena instead.
Very early in the morning (8am) or late in the afternoon (5pm) will be less crowded.
Accademia tickets are to be reserved (by scheduled time) way ahead of your visit. Later in the day is best to avoid crowds.
Save your shopping for the Oltrano district, on the other side of the Arno River and avoid the tourist counterfeits and shoulder-to-shoulder crowds. You will find authentic craftsmen for leather, jewelry, ceramics, clothing and more in the Oltrano.
Try to get a gondola ride later in the afternoon when the tour buses have left to avoid a traffic jam on the canal.
This is where locals go--way too many of them. The beaches on the mainland due north of Ischia are much less crowded.
The roads are extremely narrow with enormous traffic in the high season. Large buses, motorcyclists, bicycles and tandem 18-wheelers make it terrifying to some. The town of Amalfi is a tacky tourist trap. Go to Atrani, Cetera, Minori or Maiori instead. Head to Vietri sul Mare for the best ceramics. If you do drive, rent a small car!
Buses dump off large tour groups from cruise ships. Late afternoon visits are best. Bring a refillable water bottle and use the many fountains around the site. There is an Auto-Grill on site for lunch. Wear comfortable shoes--walking on uneven, 2000 year old paving is rough going in Pompeii.
Grand Voyage Italy's mascot, the Bocca della Verita (Mouth of Truth) is well worth the visit. It's very close to the Roman Forum and across from the Temple di Vesti. It's worth the ten to fifteen minute wait on line to test your truthfulness by placing your hand in the Bocca's mouth. If you leave with your hand intact, you're a truthful person. The chapel inside is worth a visit, too.
