I'd also recomend Old Buckenham in Norfolk. Tarmac runway.
You have to have to speak to Lakenheath/Mildenhall on 128.90 for a Matz crossing. there is also danger area 208, mildenhall will tell you if it is hot or cold. So there is something to do but not too challenging
Bacon butties, Mustang Burgers, etc etc. Parachuting to watch and then a nice trip home.
Call them first for instructions as they have a large circuit to the north to avoid being overhead Attleborough.
Let us know how you get on
