4. Rome, Italy
There isn’t much of an itinerary needed for Rome with an endless number of places to go. The city had 29.07 million bednights last year. The Pantheon would be a good place to start, progressing to the Trevi Fountain, the Spanish Steps, and the Colosseum in that order, to take in the ancient monuments that surround the city. For a more modern experience, stop by some of the Roman cafes as part of your sight-seeing. La Casa Del Caffè Tazza D’oro near the Pantheon and Antico Caffè Greco near Spanish steps are Rome’s most highly rated cafes.
