I'd go places.
From the IOW, France is very reachable, even in a PA28. La Rochelle is probably doable nonstop.
The southern UK quickly gets boring, with a few exceptions like flying over Snowdonia.
Funnily enough most passengers enjoy a trip around the IOW
One key to going places is to take others along and enjoy it with them. A PA28 is not the most passenger-friendly plane, with the way one has to crawl in and out like a cave.
