Disney N/A options are weak in comparison to other resorts. Juice and ginger ale is not a mocktail (IMO). There are a plethora of options:
-Ready to drink, De Soi, Kin, Ghia - that could easily be sold at festivals
-NA Beer that isn't St Paul or Heineken - Athletic Brewing would be a fantastic partnership in the parks and for it's Run Disney events
-Spirits for mixing - Kin, Ghia, Three Spirits, Pathfinder, etc
Closest I've seen to a decent N/A cocktail was at Citrico's, also excited to see what Summer House continues to do! They had a great selection when I lived in Chicago (before N/A was sort of cool).
