Hi Debs
The executive lounge at Terminal 4 closed at the end of June and, as far as I know, there are no plans for a new one to open in the near future.
Your tour manager is Pascal Lecrivain and he will be flying out with you. I'm sure he will be able to suggest another place for the group to meet up - perhaps a cafe or bar.
Have a great trip.
Kind regards,
Olly, your editor
