Don't forget, the lovely Bretons in Dinard consider Jersey to Dinard a local flight so cheaper landing fees.
Many plates changed for Dinard in June, Jepps & Aerads - St Brieuc too.
Dinard landing fee payment has changed too, you have to go to the firemen
airside to pay before going landside otherwise you will be forced to go all the way back through security, customs, etc and pay them. If Ryannair is there you might have a 2 hour delay, the golden harp rules dinard when there.
Perpignan might be a good en-route fuel stop if necessary.
Have a good trip
