What characters ended up being there?
I will do my best to tell where as well.
So Pluto was at the front of the park near the dreamer’s statue.
Chip and Dale were at the DJ booth right by creations, on the way to guardians.
Mickey was in Paris in the Gazebo (right by the entrance to Ratatouille) with the Aurora painting.
I think that’s all unfortunately, but it is possible I missed some since the communication seemed to be kinda of lackluster *although we asked several cast members and I didn’t see anyone else out.*
Now if you do have photo pass there are a bunch of different photo opportunities.
*these are the rememberable photopass thingy’s that I can remember.*
There was a glow up Mickey light that you could hold on the bridge that goes between France and UK.
There was also a tinkerbell light you could hold at a gazebo in UK.
Canada had pics by the totem statue.
Mexico had one close to the pyramid where it was in the background. (Also if you dislike the pop music they had a mariachi band that was a nice change of pace and made me very happy.)
Also at least 2 by guardians ship.
That’s all the major ones I can think of off the top of my head, but basically any place in the day that you would get photopass, it is likely they’ll be someone in that spot, (Just not in the 2/3 of world showcase that’s closed :/ )
I hope this was really helpful, because I know if I had some of this information, I think I’d be able to take it easy more and I mean I know it was the first party I just wish the cast members knew more as we got closer to the party. Good luck and I hope you have an enjoyable experience.
