If you had the option, I would have voted "don't care".
If you do want to go that direction, For a 4BR home, I would recommend at most *one room* with something relatively gender-neutral, featuring the Fab Five (Mickey, Minnie, Pluto, Goofy, Donald). For a larger home, you could go with two rooms, one princessy and one piratey (or Fab-Fivey), but then you rule out some family configurations. I still think more than one room might be overkill, but you'd get a better sense from your management company what does and doesn't book well.
