Paris rewards a bit of planning more than most cities — not because it's hard to get around once you're there, but because a few decisions made before you land (how you get in from the airport, how you'll get online, which sights need a ticket booked in advance) save you real time during the trip itself. Here's the short version of each.
Getting in from the airport
Most visitors land at Charles de Gaulle, about 25 km northeast of the city center, and the options range from the RER B train on the cheap end to a pre-booked private transfer on the convenient end. We've already broken down how the RER, taxi, shared shuttle, and private transfer compare in detail — worth a read before you land, especially if you're arriving late at night or with a group.

If you'd rather have a driver waiting than figure out the RER with luggage after a long flight, you can check live private transfer prices for the CDG–Paris route.

France is part of the EU roaming zone, so if you're coming from another EU country your home plan may already cover you — check before you assume you need anything extra. If you're coming from outside the EU, an eSIM is usually the simplest option: it installs in a few minutes before you fly, works the moment you land, and skips the airport SIM-counter line entirely. A short-trip data plan for a Paris visit is inexpensive enough that it's rarely worth the hassle of finding a local SIM instead.
Set up your data before you land so you're not hunting for Wi-Fi at the airport.

Paris has a handful of sights where a skip-the-line ticket genuinely changes your day — the Louvre and the Eiffel Tower both sell out timed slots well in advance during peak season, and showing up without one can mean hours in line instead of minutes. Smaller museums and neighborhood walking tours are far more forgiving; those you can usually book the morning of, or even skip the ticket entirely and just show up. If you're deciding which Paris sights need advance booking and which don't, treat "how limited is the daily capacity" as the deciding factor rather than how famous the place is.
For the sights worth locking in ahead of time, timed-entry tickets are worth booking as soon as your dates are set.

The short version
Sort your airport transfer and your eSIM before you fly, and save your in-the-moment decisions for the things that actually need them — like whether a museum's queue is worth skipping the day you're there. Paris runs smoothly once those two boxes are checked; most of the stress people associate with the city comes from leaving them until arrival.
