I just bought a fairly flat (easy to pack) noise machine at Bed Bath and Beyond that plugs in for home use and runs on batteries for cruises.....
and it is wonderful. I think it was less than $20....
It will run all night OR for 15-30-60 minutes.
I also have a small fan that runs on batteries. 2 D batteries will run it every night for a week. But those are for the hot flashes...it does not make a lot of noise....I got it at Walmart.
