I am slowly leaving the safety zone of the wide end of my 16-35 2.8 for some interior shots. It's hard though, when trying to capture as much detail as possible for real estate shoots. Kitchen surface reflections can be fun too, especially when vendors don't bother to clean them!
I know what you mean, shooting wide is easy, but its fun when you get tighter and create a beautiful composition, the tight shots supplement the wide shots nicely especially for print marketing for the properties.
