Sunscreen is among the most confiscated items at security, almost always because a full size bottle went into the cabin bag. Which forms follow the liquids rule and which sit outside it, the FAA limits that apply in the hold, and whether buying at the destination is the better answer.
Shoulders and knees covered is the whole rule in Rome's churches, and it applies to men, women and children alike. Where it is enforced hardest, what happens if you get it wrong at a timed entry slot, and the one outfit that gets you into everything.
A cabin is dry, unevenly heated and keeps you still for longer than anywhere else, which is why the right long flight outfit is built from layers rather than chosen as an outfit. Fabric choices that survive fourteen hours, why compression socks have unusually strong evidence behind them, and what security adds to the decision.
Airport screening is rarely what stops food on an international route. Customs and agriculture rules on arrival are, and undeclared fruit or meat can bring a civil penalty on top of confiscation. What travels well, what gets taken, why declaring costs nothing and how to choose edible souvenirs.
Prague has no rail link to its airport, so every option is a bus or a car. The cheapest route is one ticket covering a trolleybus and the metro, but the route number changed in 2024 and most published guides still print the old one, which is how visitors end up at the wrong stop.
Barcelona's two terminals sit four kilometres apart and the train only serves one of them, which is why the best route in is different depending on where you land. What each option costs in time, the ticket that works on the train but not the metro, and the metro that does not reach the centre.
Rome's tap water is among the best of any major European city, and the cast iron nasoni running on street corners are fed by the same supply. Which fountains are for drinking, which are decorative, and the small trick Romans use that most visitors never notice.
Barcelona's tap water is treated to European standards and safe to drink, but a lot of locals buy bottled anyway, which visitors reasonably read as a warning. Why the water tastes the way it does, how to ask for it in restaurants, and what the habit actually costs you.
Most of what makes Rome extraordinary is outdoors and unticketed, which means three days here can cost nothing in admission. Churches that function as free museums, the views that need no booking, where the drinking water is, and what the free museum Sundays really cost you.
Rome needs more time than its size suggests, because the Colosseum and the Vatican are half day commitments rather than stops on a walking route. What each day actually buys you, the timed ticket problem that catches first visitors, and how the season changes the answer.
