Of course there's always flying into another airfield around there - Coningsby might offer you a chance to trawl around BBMF (but ring first - DEFINITELY no promises as I'm not sure on their visitor policy). However, Coningsby would also allow a visit to Woodhall Spa, the Petwood House hotel and Scampton is near enough. If you get to the Petwood, ask to see the Squadron Bar as there are some interesting historical artifacts. The one that springs to mind is the branch off a tree hung across the top of the bar which came through the bomb-aimers plexi-glass window during LL evasion, I think!!!!
