Oh and they don’t limit use of a valid pass during anytime of the year, unless your pass has blocked use in the park or parks. .
My DD has the seasonal, and we were there our last day, the first day of Mardi Gras, and she was blocked out of the studios. I have the premiere, so I went into the studios to get what I wanted from there, then met up with her in IOA. We tend to only go when her pass is not blocked in any of the parks, so I did not upgrade her for one day, as it was the day we were leaving that evening. And since I go much more then her, made sense for me to have the upgraded pass.
