I for one find this a disturbing trend for Disney. Not only for reasons others have mentioned but also because, having worked for a soap company, I am aware that bar soap is actually more hygienic than liquid soap. Liquids are difficult to keep from growing organisms without adding antimicrobial/antibacterial agents (especially in warm moist environments like showers...) to maintain "freshness". But these very agents are compounding the problem of drug resistance! So when people say they prefer this method for environmental reasons, that's actually an incorrect assumption. The small individual plastic bottles are better because smaller amounts are used quickly and the bottle is recyclable. If you're not recycling your used ones, then shame on you for allowing them to end up in a landfill to begin with. Imagine a large bottle filled, used, refilled, used, refilled...it will eventually find something growing inside. I would hate to be person coming home from a park to shower only to find green slime coming out of the pump! ICK Remember, a small bar of soap will at least dry out and keep nasties from growing on the surface.
Besides, the current complimentary toiletries are an awesome take-away memory from what is supposed to be a wonderful Disney vacation. To me, this is just another instance of the Disney corporation taking away the magic that everyone comes to expect. Less and less, for more and more money, year after year isn't the way to keep guests happy. (As many companies are now beginning to find out after years of taking employee perks away, they are left with nothing but unhappy and disgruntled employees. It's never good for the bottom line...which Disney will eventually see...someday.)
Just because it's done elsewhere in the world, or by other hotel chains, does Disney have to follow THEM down this hole? Or might it be better that Disney sets the bar higher and not let others set the standards to which they have successfully done business for decades?
Having said my take on the matter, I'm keeping fingers crossed this won't be implemented at the Deluxe resorts where I tend to stay.
