I have 3 groups arriving at CDG terminal 2E at different times. Can anyone suggest a meeting point
You will need to know which separate terminals of terminal 2 people are meeting at
We were successful meeting at the CDG baggage claim. First person/group there finds a pillar or conveyer belt number and texts everyone else.
The Sheraton lobby
I'd want to know how much time between arrivals and are you staying in Paris for at least your first night? How many people in each group?
It may be simpler for each group to go directly to the taxi rank at 2E and take a taxi in to town then meet at the hotel later.
