I have just been reading on disneycentralplaza, that people have been told by CM's in the park there will be a preview of Ratatouilla weekend of 28th and 29th June for Dream AP holders.
I reallllllllllyyyyyyyyyy hope so as this is the weekend we are planning the mad birthday day trip for DS!
I have also read the studios will be open from 8pm to 11pm special for shareholders holders on the 27th for a special preview too.!
Obviously this is not confirmed by Disney but I have every thing crossed it turns out to be true :x
