I'd be comfortable with it leaving an hour prior to park open, but half hour is not enough for my comfort. And what a shame. DHS is a MESS of a back up of cars and buses trying to get in. They have this great transportation system that bypasses all of the streets and deposits you by the entrance. But nope. We're going to open it just late enough to make it unusable.
It almost makes me think they are scheduling that way on purpose. Can you imagine how mad people would be coming off the Skyliner if it stopped just long enough for them to miss the golden minute?
