We'll be staying at the Sheraton in CDG airport overnight, then taking the EuroStar to Dover... with 4 pieces of luggage. Would it be easier for us to take the TGV or a taxi to Paris Nord. By arriving by TGV, will we be able to bypass escalators & elevators with our luggage. Will taking a taxi mean more, less or the same inconvenience with luggage. And, what's it like boarding the TGV at CDG with heavy luggage. Thanks for any help!

It seems that you have something mixed up. From CDG to the train station you can take a taxi or the metro. There might also be direct buses between the two. With that much luggage I would suggest taking a taxi.
My question to you is, why stay overnight near the airport. Why not stay overnight somewhere near the Gare? At least you will be able to see a little something of Paris, maybe a local restaurant or cafe or boite de nuit!

Isn't Gare du Nord the first stop from CDG on the RER? . . . maybe Sandy meant to say RER instead of TGV...?

I think SandyR meant to say (even if not knowing it) the RER from CDG to Gare du Nord. No, that isn't the first stop, there are a couple before, but it's not far. I also think it might be fun for you to go down and stay right near the Gare du Nord rather than CDG -- such as at Hotel Terminus Nord right across from it.

In any case, you can never avoid stairs and escalators going from the RER to the train platform where you need to catch the TGV at Gare du Nord. I haven't boarded it with luggage, but regularly, and it doesn't look so bad for that route as it starts at CDG. Assuming you have two adults to handle it and the 4 pieces aren't all huge.

If there is a TGV from CDG to Gare du Nord, I haven't heard of it, but I've never looked--it would have to be some train that is going elsewhere, but I don't think the TGV line goes through the city from CDG

My humble apology... I meant the RER. And, while I'm posting, if I may ask... is it difficult to deal with luggage on the RER? Where do we put the luggage, even though it's a short ride. I was also thinking we could take the TGV to Lille, then the EuroStar to Ashford Internat'l but the fare each is 1st class - $229 ($60 for the TGV & $169 for the EuroStar)... whereas the fare for the Eurostar Paris Nord to Ashford is $189 each. I think it's a no-brainer which will opt for.

It's not difficult. The RER trains are spacious and if you get on at CDG, you should be able to find seats, and places for your luggage. The hardest part of the trip will be getting to the train entrance from your hotel. And I do agree with DougP - get the heck out of the airport and book a nice room near the Gare in advance and enjoy a little Parisian night life!

Sorry, but this is getting very confusing..there are TWO different threads from the SAME folks and different people are answering different ones in different ways.
My advice: take a taxi to the station if you don't decide to stay near there overnight..cannot quite figure out why someone taking a cruise from Dover would fly into CDG instead of London and then just stay overnight...when you get to the station you'll have plenty of time to get your luggage onto the train...provided you get there early..it may take a couple of trips on and off the train but it can be done.
If this airline routing was done to "save money" ask yourself next time if it is worth the hassle?

What you do with your luggage on the RER is keep it beside your seat or if standing beside you as everyone else crowds in on you. When you get to the gare you may have to ask the clerk to open the side gate for you since you may not be able to get your 4 pieces of luggage through the turnstile. Also for the RER be sure to retain your ticket as you must put it through the slot on the turnstile to exit the RER. Then from the RER platform you will need to find the correspondance corridor and the steps (probably) for the grandes lignes. Then up the escalator to the Eurostar. Along the way while you are trying to get luggage through there is a possibility of drawing the interest of pickpockets (I am not trying to scare you--it is just a fact at this gare, in my opinion).
Now, there is a nice 2* hotel directly across from the gare where you could stay for the same price or less than the Sheraton. The taxi to the gare from CDG would be in the neighborhood of 40E.

I disagree that taking the RER with what the poster has admitted is "heavy luggage" will be easy. "Heavy luggage" is a HUGE pain in the rear on the RER, especially if you are traveling on it anywhere near rush hour. It's hard enough just to move your own body around on those trains, never mind keep track of luggage. And the trains don't stop long enough to allow you to get a lot of luggage in or out while passengers are also entering and exiting. Also agree you are asking for trouble from pickpockets and other miscreants.
Getting "heavy luggage" onto the TGV will be slightly easier.

My thanks to everyone for the suggestions... and critiques! As to why we're flying into Paris... we're going to the Loire Valley for 5 days. I've planned this out fairly carefully. We fly into Paris, stay overnight, leave our 2 "heavy" bags" at the Sheraton and travel round-trip by the TGV, to the Loire with our 2 rollies. We've been to Paris a few times for extended stays, so we won't feel cheated not experiencing it this trip. After reading all the suggestions, I think, rather than stay at the Sheraton when we return to CDG, we'll take a shuttle or taxi into Paris and stay at the Libertal Terminus Nord, across from the Gare du Nord. That way, we'll have no problem catching the EuroStar next morning at 9:10 am. How'd I do with the planning??? Sandy

Great! Sounds like a wonderful trip.
