Looking for opinions, I know there’s no way to be sure. We arrive at CDG at 0810 on a Saturday. Is it reasonable to make a connection to a TGV train leaving from the airport at 1130? We will have checked luggage, 2 adults traveling. Seems good to me but I know CDG can be daunting even on a good day. Thoughts?
With well over 3 hours interval ( if you arrive on time), I think you should have ample time, even if changing terminals.
Your train may be a fair trek away from your arrivals area. Google will find maps of this complicated airport to help you navigate. Be sure to enter the SNCF/TGV terminal rather than the adjacent RER regional dock. It may help to know that the departure platform for your train may not be posted if you arrive early. Ten to 20 minutes warning is more typical. Step lively to find your car once posted; space for larger suitcases is cramped and challenging (my weight-lifting capacity is going in the opposite direction to my age.)
