Dear Mr. Lee,
well noted the vsit of your colleagues on May 12th.
The best is to take a taxi from Paris CDG Airport to Rouen, where you can book at the hotel Mercure Champs de Mars. Then, I can arrange a taxi from the hotel to the plant. Let me know your trip details ASAP. Due to banking day tomorrow, the plant is closed also on friday. However, I will manage from home for assistance.
Don't hesitate to contact me.
