Take the Leonardo Express to Termini then a short taxi or direct taxi to Hotel Pantheon; the hotel is centrally located near the Pantheon for immediate access to historic Rome.
Visit the Pantheon (note: church opening hours vary—typically open 9:00–19:00; there may be a small entry fee or donation outside mass times). It's an iconic, free-to-admire landmark with a remarkable dome.
Stroll to the Trevi Fountain for photos and the classic coin toss; it's always open to the public but can be crowded mid-morning—arrive earlier to avoid peak crowds.
Choose a small trattoria or paninoteca close to the hotel for a budget-friendly lunch; many options around the Pantheon offer authentic Roman dishes at modest prices.
Check into your room at 14:00, take a bath and rest for a short while to recover from travel—this helps preserve energy for the afternoon walking tour.
Walk to the Roman Forum and Colosseum; exterior views are free and dramatic, and if you want to enter the Colosseum/Forum/Palatine, check current opening times (typically 8:30–19:00, last entry ~1 hour before close) and buy combined tickets to save money.
Cross the Tiber to Trastevere for an evening meal—this neighborhood has many family-run trattorie with good prices and a lively atmosphere; reservations recommended for a group at peak dining times.
Prebook a timed entrance to the Vatican Museums to avoid long queues; museums usually open at 9:00 (closed Sun most weeks — verify your date) and a morning visit avoids heavier afternoon crowds.
Visit St. Peter's Basilica (free entry). If you wish to climb the dome for panoramic views, there is a separate fee—check opening hours which typically run from early morning to early evening.
Walk back toward central Rome along the Tiber and enjoy views from the riverside. Castel Sant'Angelo has a ticketed museum, or you can enjoy outdoor views free of charge; typical opening is around 9:00–19:30.
Take an early fast train to Napoli Centrale; book in advance for the cheapest fares and secure seats—trains depart early and travel ~1h10–1h40 depending on service.
Switch to the local Circumvesuviana train to Pompeii Scavi station; it's the most economical way to reach the archaeological site close to the entrance.
Explore the ruins of Pompeii—the site is extensive and usually open from morning until late afternoon (hours vary seasonally), so allow 3–4 hours to see the main highlights on a budget-friendly walking tour.
Have a quick breakfast near the hotel and catch a morning regional or economy intercity train to Florence; regional is cheaper though slower—book early for best fares.
See Michelangelo's David with a timed ticket to avoid long queues; the Accademia usually opens around 8:15/9:00, so afternoon visits are quieter on many days.
Admire Florence Cathedral's exterior and walk toward the Arno River and Ponte Vecchio—the exterior is free and offers superb photo opportunities; dome climbs are optional and ticketed.
See the Leaning Tower and cathedral in the compact square—climbing the tower requires a timed ticket (book in advance if desired), otherwise enjoy photos and the surrounding monuments for free.
Enter the cathedral and Baptistery to admire Romanesque art and architecture; small entrance fees apply and opening times are typically mid-morning through afternoon.
Take a return regional train to Florence and, if time and energy permit, stroll the Boboli Gardens (check seasonal opening hours and small entry fee) for panoramic views of the city.
Visit the Duomo complex (museum, cathedral, and baptistery). The complex usually opens in the morning and has a modest combined entrance fee for full access.
Catch a regional bus to San Gimignano (journey ~45–75 minutes depending on route); buses run multiple times daily—verify schedules for your travel date.
Wander the medieval streets, admire skyline towers, and visit small museums or Torre Grossa (optional fee) if open—walking the town is free and scenic.
Visit the Uffizi to see Botticelli, Leonardo and other Renaissance masterpieces—book morning timed tickets to avoid long lines; Uffizi hours commonly are morning to early evening (closed Mon often).
Return to the hotel to check out and collect luggage—if you need to travel on to another city or the airport, arrange train times now and allow buffer time.
If you need to return to Rome or go onward, book a late-afternoon regional/high-speed train; for low-budget options choose regional services, but book early for best prices on fast trains.
Have a final inexpensive dinner (panino, pizza or small osteria) or pick up snacks from Mercato Centrale for a rail/air journey—keep receipts and documents handy if traveling onward.
If you remain in Florence, overnight at your accommodation; if you're traveling onward, follow your booked transport plan. This completes the 7-day low-budget Italy loop Rome → Florence.
