Greetings All!!

Almost less then 3 months before our AKL adventure! Wooo!
Hoping you can help me in please! In the rooms I'm assuming there is a fan in the bathroom area correct? How loud is it?
I ask because at home I sleep with a fan on for the white noise, can't sleep with out.
I've been planning on buying a white noise machine to bring with us but thought I should ask first if the fan might be loud enough? Or if it even makes a sound? Would be nice to save $30-50 if I can.
And no, no sleeping in ear plugs, its uncomfortable and only in the direst or snoriest situations.
