Been to Dinard several times, always very friendly.

Generally rwy 35 is the preferred runway due to the ILS. If approaching from the northeast and 35 is in use, be careful to identify 35 and not 30, easily done the first time.
London info will generally hand you on to Brest Info at the FIR (assuming that you are using the VFR route) and you are high enough to be above the Deauville controlled bit of Cherbourg.
We route down towards Granville before turning towards Dinard. This avoids routeing through Jersey Zone as they always seem busy. Brest may ask you if you want to route through the Jersey Zone though.
Then just as you want to get on to Dinard Tower, Brest will insist that you call Rennes North Approach on 124.9 before calling the tower.
Anyway after a busy couple of minutes on the radio, you're there.
Fuelling is a bit of a pain. If you need fuel, I'd do it on arrival. The Avgas pump is located at the north end of the main apron but you have to get the key from the Fire Station at the south end of the apron. You pay for fuel and landing fees at the fire station too.
If you are staying overnight then they will probably park you on the south "P2".
Once you have parked etc, exit through the main terminal for customs etc. (Where the Ryanair pax go).
There are usually taxis outside.
When you return, head for the check in desks, at the right hand end of the check in desks are some doors for security. Press the buzzer "Vol Prive" and they will let you in ahead of the Ryanair pax, take you through the lounge and tip you out on to the apron.
All pretty easy really, except the fuel, unless you have a total card.
