Use Wanderer's Minuet whenever you are in a situation that doesn't require a lot of movement. There are a few single Duties between 52 and 60 where you do not want to be using Wanderer's Minuet, unless you enjoy being beat on by <insert favorite monster here>. I've never seen a reason to run around when in a dungeon instance unless I'm avoiding mechanics, so it's never bothered me that I can't do so when WM is up.
