Jasper We paid the same £160 fee for National Trust membership and did most of the Hampshire sites last year which paid for itself. I am a bit on the fence about NT. The sites are usually old houses and think the gardens are excellent in the summer. Good for birdwatching and butterflies. The sites are less appealing in the winter and I do feel that the historical information that is available can be very lightweight. The Roman villa at Chedworth is probably the worst example as there is not much historical context. If you read about the site , there's nothing to put Chedworth in it's true historical context. My favourite old house is Hatchlands because of the Cobb keyboard collection. Absolutely brilliant.
We like Kingston Lacey , but because of the gardens ., the snow drops are beautiful , though I admit they are not exactly there are all year round . Just walking around is so peaceful . Same situation for us with Mottisfont Abbey , walking by the stream looking at the fish REALLY relaxes me . Not set foot in Kingston Lacey house and have no real desire to . Lanhydrock house on the other hand was amazing , a kitchen etc to die for . Also Chatsworth house and Gardens are amazing . While we were there , they were setting the place up for a Banquet . The preparation was incredible !
