Pulled from the thread:
the iced cappuchinos in the MK were snack credits if you're on the dining plan. They were also snack credits at Writer's Stop in DHS
MK
-Cosmic Rays in MK has an iced capucino that is quite refreshing
-There was a place in Adventureland near Aladdin's Magic Carpet's that had some.
-Sleepy Hollow and Enchanted Grove had iced cappuchinos
Epcot:
-I think the coffee stand in FW near Universe of Energy does iced coffee as well
-coffee stand in Canada in Epcot has iced coffee
-offee stands by the Universe of Energy, near the entrance to World Showcase, next to Italy, and I think also near the UK that had iced espresso drinks (iced lattes, iced mochas, etc.) I like the iced mochas the best.
DHS
-At the Hollywood Studios, both Starring Rolls and Writer's Stop have iced coffee drinks
-Writer's Stop also had iced espresso drinks
-Tower of Terror exit
