I always carry 20 feet or so of 6 to 8mm rope. My daughter even does this and has found it handy when she has fallen on a hard slope and wants to walk down the slope and tie her skis to the slope and lower the skis down the slops so she ahs her hands free. I always think of rappelling off the chaif if it is stuck, I can always dreem. Just an added adventure, LOL.
