Can I suggest Goodwood too a nice central South Coast location and the home of the Silver Spitfire and Boultbee Aviation with their Spitfire flights for sale?
Also, there’s the Spitfire cafe at Popham near the A303 (former home of Charles Church’s Spitfires) good for bikes and bikers and with regular aircraft-related events.
Sandown Airport on the Isle of Wight (the home of Airframe Assemblies whose main work is the reconstruction of Spitfires of various marks) has a great cafe/restaurant for anyone who wants a foreign trip one day…
Not so Spitfire-related but the Army Air Corps museum just South of Andover has a great cafe next to an active airfield too. I suspect many of my trips will be to similar locations – but then I live within half a mile of Boscombe Down and every September 14th I get my own personal 20 minutes Spitfire flying display for BoB day (it’s my birthday and whatever you say the dislay is for me, you hear!).
Finally, the Tuesday Evening events at Poole Quay are starting up again in the next few weeks I believe. I shall be there on the Cafe Racer one evening at least for sure.
Biggin on the Bump is a little far from Wiltshire to be easy I’m sorry to say but if you have something a little more South central or in the South West then I shall be there.
