Operation Stack on M20 for Easter getaway

I have spoken to a colleague who has told me that they are planning to implement Operation Stack from MAIDSTONE to FOLKESTONE from Wednesday 23rd March.
Priority traffic will be given to motorists for the Easter getaway as most have pre booked their crossing. The Calais terminal will still only have the two berths operational so LONG delays are anticipated for Trucks outward bound from Wednesday.

I hope he is wrong on this information but we will see…
