For some who don't use the fridge then I absolutely agree it's no big deal. Not a big deal for me, I have ability to solve it. But it is for others because it can greatly affect their trip financially.
And Dis is a small portion of the people at these resorts expecting a fridge. For many families it is an important amenity that saves them a good bit of money. Breakfast foods and making sandwiches for a week long trip is saving a lot of money. What if you showed up not knowing, didn't plan on hundreds of dollars for that food and you had a food delivery on order coming.
Disney resort prices are climbing to a point many families really have to think if they will stay on property. Disney is competing with hotels just outside the property with free internet, fridges, microwaves, free breakfast, even two room suites for less than they charge for a value some seasons. As their prices climbed the fridges and internet became included in the prices. This wasn't planned but how they handle it is critical. For me, no fridge means they owe folks a daily credit to help offset meals they planned to cover with that fridge and owe them timely notification prior to departure date if their resort is still affected to cancel food orders and be ready for extra eating expenses.
Pre-fridge days we either rolled a mini fridge on a small luggage rack to the room or brought an xtreme cooler that ice barely melted. We like to come often and to do that we try to save for the next trip. Breakfast in our room (fruit, juice and yogurt), sandwich supplies to carry into parks so that we can eat a nice table service meal each evening. Even the times we were on dining plan the fridge was great for getting fruit and juice the night before for our breakfasts and our desserts we couldn't finish for snacking later. While the mug is a nice thought I'm not walking to the food court at 10pm when I feel like a cold soda or beer. I go to my fridge.
Coolers will be a great alternative BUT (1) most won't even know to bring or order one (2) many can't get off property to get one (3) there isn't going to be enough ice in those machines to keep every cooler iced. I can see it now, people in long lines for the ice machines hoping it doesn't run out before they get there.



Installing them is only half the problem. there aren't just 30,000 plus mini fridges sitting in a warehouse hoping to be bought. Disney had better get their thinking caps on how to handle this with care. This potentially could get ugly at the front desk
