Who even knows what's in those containers? It's some white stuff that kinda seems to be a cross between milk and half and half. At some of the resorts, like at contempo cafe at contemporary, the vat of it is big enough it simply cannot be actual milk or half and half.
Not sure we'll ever truly know what they have to put in the coffee...
And yes you can get coffee, though if I recall correctly, at Kidani their set-up isn't as fancy as at other resorts.
DH and I are not coffee drinkers, but do enjoy our tea every morning. I can't stand cream in tea. I can honestly say that the milk does indeed taste like milk in the containers listed as such.
