I would like to know that to. We like the noise from a fan at home. So I hope you still get that kind of noise from the wall unit.
Our family can not sleep without noise so we ALWAYS travel with a sound spa thingy. I have heard them called several different things but ours is also a alarm clock and was around $20. We love it and never go anywhere without it. It's pretty small so it's easy to pack as well.
