We went last night. The meal vouchers had to be rung up individually. So if you had a group of 5, that would be 5 separate transactions. Slowed service down a lot. Hope they perfect this system before the next event. Despite that, we loved having more choices for everyone and it was much fresher than the mass prepared hot dogs or nuggets from past events.
Ice cream bars were still available in two locations in Future World. The only place we could find to get drinks once the park closed was the merchandise locations on the bridge to World Showcase. (Near the DVC booth). No other retail location or cart was open.
