I really think this is a swing and a miss for Disney. The bottles are just asking for issues...from cleaning, refilling, theft, etc. IF they wanted to truly reduce waste, they should have gone with smooth hand-pump based dispensers with replaceable bags/cartridges as used by medical offices. Once the bag is out, you replace it (which includes the no-touch dispensary for the soap).
We are used to hand pumps on Carnival and their refills, but honestly expected better on Disney. Oh well....time will tell as to how this goes!
Something like these with a cute Disney shape/design would have been far safer in every aspect!
