You seem to not understand how malls work. Stores sign contracts wanting to make money ASAP. Zara, Under Armour, UGG and the many, many more locations that are OPEN weren't going to not make money when the store was finished. A mall opened near me in Tampa last year and it was the same thing. If you were ready, you opened with the mall. If not, you opened over time. If Disney told the 20-30+ vendors that opened "you gotta wait for the other guys", you better bet there would've been problems.
Also, how are they misleading? They have stated publicly what the deal is and signs are on the windows for the non-open stores. What did you desperately want to see that wasn't open? I mean of all the complaints, this is the pettiest.
