What isn't big and isn't famous but is worth visiting? Our hotel has a list: go to the fruit vendor with a cart instead of the grocery chain. There's a museum in the city, but also a block away there's an artist with a home gallery...
Hotels that want to be on the "local love" should have a list of nearby little activities and shots that help the community. Maybe volunteer activities? Put it up here, and also have it at the hotel front desk.
