Hint for VFR flightplans around Europe: In Route section put in as little as possible ie, just put in the FIR boundary points (a lat/long will do if there isn't a waypoint) then DCT. The less you put in, the less chance of a rejection on a technicality.
I'd say the opposite! I've had German AIS reject VFR FPLs on the basis that the flight time between consecutive waypoints was 35 minutes -- the maximum permissible is 30!
