Cranfield, Luton (via the VFR corridor), BUR (special VFR through the Heathrow zone), Farnborough, Shoreham.
On the way back;
May, Thurrock, Panshager, between Stansted and Luton, home - with a possible stop at Headcorn (well worth a visit and free landing with fuel).
A circular route round all the zones so a bit more interesting, and some good scenery as well.
Let us know what you decide.
(In case you decide against OB)
