yeah the map should be updated next Wednesday
The locations are pretty straight forward though. Storytellers meet at their respective pavilions. The only one you won't clearly see while walking will be the UK one, he's in the back by the gazebo.
Food locations: Promenade is the beginning of World Showcase, so around the 2 gift shops on either side before you hit Mexico or Canada. The Odyssey building is between Test Track and Mexico pavilion, close to first aid/baby care center
The Fountain of Nations is the fountain right behind Spaceship Earth
