What's the best way to get from CDG airport to Paris hotel?

Don't know how many in your party but if you have more than yourself it sounds like a money maker for your travel "agent".

There are minivan taxis in the ranks at CDG. If you reject anyone who approaches you independently and only take an official taxi, you should be fine. Write down the name and address of your hotel, including the arrondissement, to hand to the driver.

I swear up and down my allegiance to: Roissybus & les cars Air France Roissybus takes you to the Opera Garnier (where you can either cab or take the metro. I suggest the metro unless you have tons of luggage) http://www.ratp.fr/en/ratp/r_28065/roissybus/ Les cars Air France has different lines.

I've lived in Paris on and off for decades and have never had a problem. Always use official taxi stands or call official companies as stated. Taxis are highly regulated. However there are illegal cabs that may search out tourists. Late at night 3 years ago in a long taxi line, we were solicited repeatedly by illegal taxis, something that has popped up with the population influx from eastern Europe. All the drivers had accents. People didn't go with them. BTW, the same situation exists at Dullas Airport in DC. Warning signs tell people not to accept solicited rides. Is 58.22 reasonable? It depends on how many in your party. A taxi is about 60-70 each way, maybe a little more by now, and can carry several people. You can do the math. One other consideration is that a lot of shuttle van services have received scathing reports here. You'd have to do a search for vans. Would it be worth it if you had to call a taxi at the last minute because the van isn't getting there in time to pick you up for the plane? My personal preference is the RER for 10 euros or a taxi. Or Alexander's buses.

Our hotel made arrangements for the taxi, and as I vaguely recall, it was around $60. for 2. But!.....we waited at least 40 mins.

your options: Taxi: only worth it if you are old with knee problems or you have the money to spend and won't feel like you wasted it or it's at some weird hour like 1am. 4+ people who individually pay for themselves. $65.00 max Train: RER B. Super easy and simple, the method I love to use. But like any big city, keep your hands on your stuff, or you might be targeted by thieves. But I have taken it numerous times and felt completely safe. $12.00 per person Bus: Roissybus is $13.00 per person takes you to the Opera area. Les Cars Air France is $25.00 per person and takes you to Arc de Triomphe, Montparnasse and Gare de Lyon. Bus 351 is $7.00 per person it's slow and it takes you to Paris Nation RER/Metro station. have fun!

I would recommend taking the Roissybus to get you to central Paris-it takes you to the Opera House. Since you'll probably be tired and overwhelmed by bus route choices and metro lines from there, I'd just get a taxi from the Opera House to your hotel. As I remember, there's a taxi stand right there. Then rest up and figure out the metro the next day!

Take the RER B to central Paris, $12, 30 minutes.

so thats about 120 dollars( about 98 euros) ,, is that for a private van, or a shared van. Its a rip off for a shared van, since a private taxi will run between 45-55 euros( about 68 dollars for 55 euros) . Travel agents usually recommend services that they get a kick back from,, I haven't used one in many decades. The offical taxis from the taxi stand are absoulutely fine! . They will add one euro for each big suitcase,, off the meter, so don't freak out thinking they are padding the bill they are not! BTW Depending your your hotel location( which you could mention for more specific advise) you could take the RER and simply walk to hotel. Unless you have kids or a lot of luggage the RER is a great option.

We took the RER B to central Paris and walked to our hotel. Fast, cheap and easy. If the hotel had not been close, we'd have taken a taxi from central Paris.

I agree with Dianne. We were recently in Paris and took RER to Luxombourg Gardens and walked to the hotel. There were steps to deal with getting out of the station so consider how heavy your luggage is and if you can handle it on stairs.

RER B train is fast and efficient, BJT be sure you know where and how to purchase your ticket to get on to the train. The ticket maches are not hospitable to US debit and credit cards (no chip I guess?), and there is a total lack of information as to which entrance (at St. Michel and Notre Dame) to use to find the ticket machine. There is a ticket booth, but it was not manned when I was there. Also, there are many steps to the lowest level of the station to get to the RER B train to CDG. Lucky for me, two ladies took compassion and their time to assist me on what was fast developing into a nightmare!

On June 2 we did the Roissy Bus and taxi option. We bought the bus tickets at the Information at CDG. The bus was right outside. It cost the 2 of us about half of the cost of a taxi and no stairs to climb up or down. Caveats...the bus was super packed with barely standing room...all from arrivals at the airport around 10 on a Saturday morning AND the taxi stand is about 3 streets around the big Opera square/multi-street intersection...somewhat hard to see in our jet-lagged state.

Private car service is not likely to be cheaper then a taxi, and yes, I know and have used one twice in Paris, but for certain reasons( RER strike and arriving with child),, I normally take RER and or taxi. I think there is alot of false hearsay about taxis in Paris. And some of it is simply tourists are clueless about fees, how things are calculated and jump to conclusions that they are being ripped off. There is nothing wrong with taxis from airport as long as you get one from the Offical Parisein Taxi stand, then you will get a properly licenced and metered taxi. Fare will run from between 45-55 euros ,, unless you hit super bad traffic or have alot of people and luggage ( they do have taxi vans that take up to 5 or 6 people but you are charged an extra 3 euros per person for , 4th, 5th and 6th, and one euro per suitcase other then carryon These are fees added after meter fee and are legal and permitted. Do not go with any taxi driver who approaches you, only take a taxi from offical stand. I have used Shuttle -Inter twice, they were fine, I liked not having to pay up front.. worst case scenerio if they were not there then I would have grabbed a taxi! PS Always WRITE down your destinations full name and address , your hotel may have the same name as another one( there IS more then one Hotel St Pierre, look it up, and they are in two completely different areas of PAris) , so you get the drive around, while driver trys to find it,, the zip code is included in the address and is always important to include as its last two digits indicate which arrondissemont ( neighborhood) the street is in. Plus it just so much easier to hand them a piece of paper then worry that your pronouciation is confusing.
