They do have to do something about it because they are leaving money on the table. When everyone is in 100+ minute lines, they are not buying things. Like Disney, Universal wants you out of lines and eating, drinking, and buying because that's where they make their money. I think the hesitation with the 2 park idea is that the most natural transition goes through a land that is not allowed to participate in Seuss, and the next land is Marvel (and who knows where that stands?) Changes have to be made for next year or else I won't go. To wait in those lines only to be rushed through houses and miss scares is not what I paid for.
