Most people head straight for the Colosseum and stand in the huge line waiting for eternity to see a glimpse inside the impressive ruins. My tip is instead of heading to the Colosseum first, go to Palatine Hill in the Roman forum (next to the Colosseum), where you can buy a ticket that gets you into both the Colosseum and the Hill. You can either have a look around the Hill or, if you can’t wait any longer, head to the Colosseum and just walk straight through the gates. There is never a line at the Palatine Hill for a ticket as people already have their ticket from the Colosseum.
