I use a CPAP machine and I just used the ships tap water. I did not see that just 7 days of their water hurt it in any way. But if you can bring your own water then you won't have to worry about it. We also took a power strip because we was worried about the plug in situation. Our stateroom attendent gave us an extension cord to plug my machine into, so everything worked out just great!
