I would clear customs at Lydd (a small landing fee for ULMs and just west of Dover) and then head across to Weston Zoyland. The easiest route is to fllow the coast to Shoreham and then head NW. If you call for transits of any controlled airspace, they will normally help you.
Weston Zoyland is a microlight/ULM field and you will be made most welcome there.
