My take-away from the other thread is to wonder what people's expectations of a day out/weekend break are. For me, if I'm in a city or town, it will be museums, galleries - anywhere with world class art is going to make me happy, but interiors of churches and public buildings are always interesting, even in smallish places. Walking around central areas is also fun, weather permitting - for that, reading the guidebook and / or getting a tour adds a lot. In London, I really enjoy the river boat operators (rather hokey) spiel, just to tell me what the buildings we're passing are, and to get a view of how the working river and the city have interacted over the centuries. I am a cheapskate and not much of a drinker, so shops and pubs don't feature much.
If I'm in the country I am interested in plants, so usually have something to enjoy. At the sea, I love big views, open space, that sense of the liminal, but also pottering around rockpools and the high tide line.
In my most disappointing holiday place, west Cork, I had no car so was confined to one spot on a peninsula where the views were all of closed-in narrow water which wasn't what I needed right then - I'd just landed a permanent job in a place riddled with bullying and manipulation and felt trapped, so I definitely took the problems with claustrophobic views with me - I might visit again and love it (and the awful-place job did help jump to something better later on).
