it seems it will be up in the air for most of you trying to go in october and november, but like others have stated, they do have unannounced previews before the AP previews. back when Everest was not open yet, we werent expecting to see it running when we had walked into the park, and this was the last week of february mind you and the official opening wasnt until mid april of that year i believe, and they had fast pass running for it as well. so have a little disney faith, you never know what can happen down there.
