April, 2023: We filled our refillable bottles with ice water from a bunch of different self serve soda fountains at QS restaurants, Backlot Express in HS, Connections Eatery and Regal Eagle in Epcot, I remember that Restaurantosaurus at AK and Rosie’s All American at HS had this and I heard ABC Commissary but we never went there. I think Casey’s Corner at MK too. Cosmic Rays at MK gave me two big cups of ice and then it was easy to fill from the refill fountain, other places had cups of ice water ready to be handed over to anyone. PJ’s Takeout next to Hoop De Doo had self serve ice water. We also did a lot of refills at the QS restaurants at the hotel before heading to the parks. We kinda treated it like a wilderness hike with regards to water…whenever you find a source, drink whatever you have at the moment and fillerup!
