Most Italy mistakes are about pace rather than landmarks. GetYourGuide city guides show where time is easiest to underestimate.
Mistakes 1–5: pace
Do not stack the Vatican and Colosseum, steal a Florence day for four towns, treat Como as a quick add-on, squeeze Amalfi into hours, or judge Venice by straight-line map distance.
Mistakes 6–10: tickets
Do not rely on old hours or prices. Recheck the date, meeting point and inclusions; allow for security and leave space between timed entries.
Mistakes 11–15: logistics
Avoid excess Venice luggage, coastal plans without buffers, ignoring seasonality, changing hotels nightly, and accommodation with poor links to early trains or tours.
