Colosseum
Start here, first thing, before the heat and the queues. One standard ticket (around 18 euros, about $20) covers the Colosseum on a reserved time slot plus the Roman Forum and Palatine Hill, valid for 24 hours with one entry to each, so buy it online days ahead: it sells out from spring through autumn. Book the earliest slot you can and go straight to the upper tiers for the view down into the arena. The arena floor and undergrounds need a pricier Full Experience ticket.
