Fill Water Bottles at Self-Serve Stations at Resort?

[DisneyGirlTer]

Looking to plan for an upcoming trip -
Are we able to fill up our Yeti water bottle with water at the Self-Serve Stations at the resort?

(Side note - we will be buying refillable mugs for coffee/soda; only looking to fill our Yeti mug with WATER)

We use to lug around water bottles until our DD told us you can get free ice water from any of the QS's & even from Starbucks in the parks.
