I'm heading over for the full week this year to go and nose around the scrutineering. Tunnel is booked Sunday evening 8pm'ish, staying in a nice seafront hotel in Calais and then being pitched ready for the afternoon in town on Monday.
If you're going to Caen Rich have you stopped off at St Michaels Mount before? We dropped by on the way to Nantes in September and the place is very spectacular, especially early doors with the mist still on the causeway.
Phil - we always visit it on the way back, but this year we'll be staying on for a couple of extra days and hope to stay in one of the hotels on the Mount itself.
