CPAP distilled water

We have a trip on the Disney Destiny this summer and signed up for the distilled water service for CPAP machines, but does anyone know what kind of water they provide? Any pictures would be really appreciated!

I ask because we've stayed at hotels that provide distilled water as part of their resort services but it was always the distilled Smartwater that has minerals added. Asking so I know if I should bring my own ahead of time.
