I called a couple of weeks ago and this is what I was told. The people that stay at one of their hotels, get in early every morning and unlimited express passes(just like fastpasses). The people that purchase the multi day tickets, get in early Sunday and Thursdays to Universal Studios and Monday and Wednesday to IOA. They also can choose 3 express passes at a time. One day tickets do not get too much. Please let me know if you have any questions. And I hope this helped.
