Best way to get from CDG to my hotel in Paris?

The easiest way is to just get in the line for a cab.

Or you could email your hotel to see if it will arrange for a car service to pick you up.

The RER B train line from the airport to Paris was easy and avoided the bottleneck of traffic. This site may help: https://parisbytrain.com/charles-de-gaulle-airport-cdg-to-paris-by-train/

You might just check with your hotel and see if they have a relationship with a particular shuttle service &/or have one they recommend, I have done this a couple times. Just be sure you have specific instructions where to meet the car or van and also who you call or text when you have picked up any checked luggage.

Where's your hotel? The fare is a flat rate so we can tell you how much a taxi will cost.

Will you be at the end of an international flight? That makes a difference to me as when I am fuzzy and jet-lagged I prefer taxi over public transportation as a solo female traveler.

Take a taxi from the official taxi queue. Fares are fixed for up to 4 people and luggage at 50€ to the Right Bank and 55€ to the Left Bank. Taxi drivers are not tipped.

Private shuttle services are infinitely less reliable and will cost more than official taxis.

My hotel is near Les Invalides. In the 7th arrondissement. The Cler Hotel. 24 bis Rue Cler, Paris. 75007.

I'd take a taxi. I stay near there and I'm sure you'll enjoy the area. The taxi is 55E flat rate from the official taxi rank at CDG.

You could do this by RER and Metro but you'd have to make a couple of changes and that wouldn't be fun for me!

Enjoy the Amorino down at the far end of the street for gelato/sorbetto! Yum!

Yes, rue Cler is really not convenient by RER train as two changes would be required to get to nearest metro, so that's one more vote for the cab! And not Uber, because if the driver can't find you for some reason in the busy pick-up areas, they'll call you and start asking questions in French.

For the Metro, RER and other mass transit, this site's interactive search will set up travel routes during your whole stay in Paris. Google Maps does similar planning although with less advice on fares etc. Try it from home now so you will be prepared for touchdown at CdG. Paris By Train is also useful with its photographic tours of stations.

We have been to Paris several times and always use the RER. Just watch for pickpockets, they are awful there.

When I arrive at a major city after a long Transatlantic Flight, I usually have a plan A and a plan B.

Plan A is if I am feeling pretty good after the flight. I will take the public transport option into my hotel. In this case it would be a combination of RER and metro for you. I carefully research the connections in advance.

Plan B is if I am feeling a little insecure about the public transport option or really not feeling at the top of my game after the flight. It is always a taxi to the hotel. Once again, I research any special info I should know about taxis in that location and make sure I find the official taxi rank.

don't 'watch' for pickpockets; be pickpocket proof. While sometimes you spot them at work, mostly you only realize you were near one when you reach for your wallet later and it is gone. Don't carry a wallet in a pocket including a front pocket; don't keep valuables in backpacks, the pickpockets buffet. I use a money belt under my clothes in transit; this is a body safe not a purse; you don't access in public. Once at your hotel stow your valuables in the safe and only carry one card and some money in a secure place -- neck wallet under shirt, hidden zipped pocket inside jacket or shirt, cross body purse you keep your arm on when in crowded places.

And on transit never set down a purse, computer bag, or backpack without keeping your hand on it; don't do this when buying tickets at a train station or checking into a hotel either. Hotel lobbies and ticket windows are target places for thieves when people are distracted and set their valuables down.

Be pickpocket proof then don't worry about it.

My hotel is near Les Invalides. In the 7th arrondissement. The Cler
Hotel. 24 bis Rue Cler, Paris. 75007.

As an initial place to look for directions between two locales, use google maps.

If you have to change trains and you are not accustomed to taking public transport on a regular basis, you might want to take car service from CDG. Find out what the car service options are as they may be a lot cheaper than taxis as is the case in London.

Taxis are fixed rate (55€ to rue Cler from cDG), and car services are more expensive. Paris is not, decidedly not like London in this regard.
