Colosseum
Give the ancient city its own first day, and start at the arena before the heat builds. The standard ticket is 18 euros, about $20, and it covers the Colosseum on a reserved time slot plus the Roman Forum and Palatine Hill, valid 24 hours with one entry to each, so book online days ahead because it sells out spring through autumn. Take the earliest slot and climb to the upper tier for the look down into the arena. The floor and undergrounds need the pricier Full Experience ticket you can skip on a first visit.
