First timer Question - Refill Cups

[Going2Disney]

I have seen posts about cups that you buy at your hotel that are refillable. Then there are posts that confuse me. Can we only use these cups at the resort or can you use them throughout the parks as well to obtain free refills? Please and thanks.
