Hi,
You're welcome.
Are you flying to CDG? After you land, follow the lines to Immigration, where your passport will be stamped. Baggage claim can be tedious, I've experience both delays and what I would call "normal" times when the first bag/piece is thrown out.
After that pay attention to the signs. The last time I landed at Paris CDG was in 2015, still I missed a sign, took the path towards the RER B. Unless no one is manning ticket counter, I suggest going to a counter, don't bother with a machine. I would rather wait in line (I happened not to in 2015) and deal with a person when buying the RER ticket.
You want the RER "B" which takes you to Gare du Nord. Buying from the ticket counter can be done with a credit card. I paid in cash. In 2015 the price was 10 Euro, might be more now.
Upon arriving at the terminus, Magenta/Gare du Nord (the stations blend together, sort of like Kings Cross/St Pancras in London), you need to go to the ground floor, ie street level. Take the escalator, unless you want the exercise of lugging the luggage up the stairs.
Once up the stairs you're in Gare du Nord, people swarming all over, could be daunting, just as in London or Berlin Hbf (central station) or Hamburg Hbf. Outside is the corner of Rue St Quentin and Rue de Dunkerque. For me arriving in Paris, this is it as my hotel is in this immediate area I just walk over there.
The lines for a taxi are your right, you'll see that. Be aware of the scammers if you take a taxi. Usually you have wait in line. Where is your hotel located?
