What is the best time to visit London?+
May to September for warmth + long daylight (June sunset 21:30). July is hottest (24-25°C) + most crowded. April + October are great shoulder seasons — milder, cheaper, fewer crowds, decent weather. Avoid November-February unless you want Christmas markets + low hotel prices (accept grey + cold). December is magical for Christmas lights + ice skating but expensive.

How do I use the Tube without getting scammed?+
Use a contactless bank card (or Apple/Google Pay on phone) — tap in + out at the yellow readers on turnstiles. No Oyster card needed for short stays (in fact Oyster is being phased out for tourists).

Is London safe for tourists?+
Yes, generally. Violent crime against tourists rare. Petty theft (pickpocketing, phone snatching) on the rise — keep phone on a strap + bag zipped in crowded areas. Tube + major attractions are safe.

Emergency: 999 or 112.

Is Brexit affecting London tourism?+
Practically, very little for tourists: no more EU freedom of movement means EU travelers need a valid passport (not ID card) + ETA authorization. Prices remain competitive. London stays fully international — 300+ languages spoken. Customs lines are slightly longer for EU arrivals. Duty-free shopping has returned for EU travelers.
Is tap water safe in London?+

London vs Paris — which is better?+
Both are world-class but different. London: free museums, world theatre, English-language ease, diverse food (especially Asian + Middle Eastern). Paris: best classical art (Louvre, Orsay), romance, architecture, pastries, café culture. If language matters or you want breadth over Romance-specific culture, London. If you want romance + specific art + formal European elegance, Paris. Ideal: both via Eurostar (2h 15m, £80-250 one-way).
What about the weather — is it really always rainy?+
Myth overstated. London gets about 106 rainy days a year (similar to New York). July is sunniest + driest; January wettest. Rain is usually drizzle lasting 30-60 min, not day-long downpours. UK heatwaves now hit 35-40°C in July-August. Dress in layers; always carry a packable rain jacket.

For big-name musicals (Hamilton, Les Mis, Phantom, Lion King, Mamma Mia, Wicked): 2-3 months ahead for weekend evenings, particularly good seats. Play openings + limited runs: book weeks ahead. Same-day discounts: TKTS booth (Leicester Square, opens 10:30) has same-day 25-50% off; TodayTix app lottery tickets ($40-60 day-of). Weekday matinees cheapest + quietest.

London has 3,500+ pubs. Essentials: Sunday roast (12:00-16:00 best experience), cask ale (Fuller's, Sharp's, Timothy Taylor's brands from CAMRA-approved pubs), Scotch eggs + pork scratchings, and casual people-watching. Closing time 23:00 weekdays, 00:00 weekends (some later-license). Order at the bar, not the table, unless ordering food.
What should I avoid in London?+
Avoid: buying theatre tickets from touts outside venues (scalpers, often fakes); cash machines in off-license shops (card skimming risk — use bank-branded ATMs); airport taxi touts inside terminals (use Elizabeth Line or official cab rank); the "red bus tour" tickets at £35+ (London buses are £1.75); street gambling games (three-card monte); pickpocketing hotspots (London Bridge tube, Oxford Circus, Leicester Square Saturday nights).
