Seriously 1st world problem, I think from what they were saying every day the aim is to reduce their rubbish impact as they now have the metal water carriers in every room and no longer hand out thousands of plastic bottles, a very welcome move copied from river cruises that have done this for some time. Multiple small bottles of water are ridiculous items to carry and I can see them slowly getting rid. Given Perrier is no longer whet is was and has had so many problems why would you want to drink it? Water is water and as recent studies have show mineral waters can be less pure than tap!
BTW I didnt see them run out of anything on our recent cruise
