Just got home...Did 1 day with express...and 1 day without express. On the day with it, we had everything done except mine kart madness by 3:30 (thats with eating lunch, and doing both shows). On the day without it, we still did a good bit, but by 1PM lines were more or less over 90 minutes for pretty much every ride except Monsters Unchained and curse of the werewolf. Even fyre drill was pushing 90 minutes. Then the thunderstorms came and basically shut down the whole park for 2.5 hours. If you're going during rainy season, I would get it just because of that factor. A few storms and your day will be wiped out, but it could at least be salvaged with express during the non rain periods. They actually were giving 50% refunds yesterday due to all the ride downtimes and storms (we personally didn't ask for one, but several people we talked to that night said they went to guest services and received them, and I saw other people in the facebook group saying the same thing.
