Colosseum
Start here at opening, before the heat and the lines. One standard ticket (around 18 euros, about $20) reserves a Colosseum time slot and also covers the Roman Forum and Palatine Hill, valid 24 hours with one entry to each, so buy it online days ahead: it sells out from spring through autumn. Take the earliest slot you can and head up to the tiers for the view down into the arena.
