What are you interested in knowing?
I will say that grad nights will effect the crowds in BOTH parks, there is no escape. Schools have the choice of the party only, DCA & party or park hoppers & party. The Grads will be in both parks and unless the individual school requires them to, they may stay at
Disneyland until the park closes before moving over to DCA for the rest of the night. Those will park hoppers will likely hop over to Disneyland when DCA closes at 9pm. And those without hoppers may choose Disneyland as their park for the day over DCA because DCA will close earlier then normal.
