80 cities. Every continent.

Things to do in
every city on earth.

Straight answers, curated lists, and in-depth guides —
backed by live local data. No ads, no sponsored rankings, no fluff.

TTDI is an answer engine for travel. Every page answers one specific question — when to visit, what a day costs, where locals eat, whether it's safe — in the first fifty words, and then earns that answer with the climate record, the current exchange rate, and a catalog of places we can stand behind. No stubs, no sponsored rankings, no filler. A page exists because travelers keep asking its question, and for no other reason.

July

In season right now

Cities whose best-time verdict names July among their best months — with the month's real numbers, not a brochure's optimism.

From the question pages

Straight answers, verbatim

The newest verdicts — each one self-contained, sourced, and quotable exactly as written.

eSIM providers — Taipei

Airalo ranks first for Taipei eSIM coverage in 2026, starting at $4.00 for 1 GB on the Chunghwa Telecom network. It holds the strongest signal across the island, from underground MRT platforms to the hillside districts above the city center. The tie-breaker is activation speed. Scan the QR code before landing at Taoyuan, and you're connected by the time you clear immigration.
eSIM providers — Las Vegas

Airalo tops this list for Las Vegas visitors in 2026, with plans starting at $4.00 and reliable T-Mobile network coverage that holds up inside Strip casinos and along the Monorail corridor. The tie-breaker is activation speed. You scan a QR code at Harry Reid International Airport baggage claim and have data before reaching ground transportation.
Cultural etiquette — Abu Dhabi

Abu Dhabi enforces modesty laws that carry real fines. Cover shoulders and knees in malls and public spaces. Public displays of affection risk arrest under UAE federal law. During Ramadan, eating or drinking in public before sunset is a prosecutable offense. Greet with 'as-salamu alaykum' and accept Arabic coffee with your right hand.
Cost per day — Istanbul

Istanbul runs about $30/day on a tight budget (hostel dorm, street food, Istanbulkart transit), $90/day midrange (three-star in Beyoğlu, sit-down meals, two paid museums), or $300+ for five-star Bosphorus-view hotels and private airport transfers. The lira at 47.35 to the dollar currently works hard in your favor.

Long-form, named-author deep dives — the pages we'd hand a friend the week before their trip.

Venice
Venice Restaurants: What's Worth It

Venice runs on two dining currencies. The standing espresso at a neighbourhood counter costs a coin. The seated room on Piazza San Marco charges for the address. This guide names twelve places across both tiers, with hours, alternatives, and the honest word on who each kitchen is right for.
