On a busy day the lines get long in this order, Tram Tour, Simpsons, Mummy, Jurassic Park.
I don't know about the new Terminator ride but supposed to be quite good. The other shows get large crowds but don't be scared off by them. The seating areas for the shows are large and almost always the entire crowd waiting outside will get a seat.
They have an all you can eat meal plan that can be a good value if you're staying a long day. You can go through the restaurants line as many times as you want even just for a snack.
Theres also refillable mugs that can be a good deal on a hot sunny day.
