I think there will be an opening ceremony but not sure other than that. For the 25th the had all the characters and dancers wearing a differents costumes from the different parades over the years which was really cool.
Thanks Disfa10! It's interesting that the CM greeting is at both parks! Are the freebies for TDS and TDL different? I just want to make sure I understand are you saying there will there be an opening ceremony at TDS as well?
