When HHN begins, is the rest of the park open/available to ride rides or are you locked in that area?

Simpson's closed early too

Harry Potter and Despicable Me were closed....everything else was good. We did transformer ride...which is AWESOME! We also did Mummy & Simpsons. I will say, Insideous had an hour wait on Sunday, so Fri and Sat would be 2 hr wait minimum... We did all the mazes no problem. Started at 7, finished at 12. American Horror Story and The Shining were awesome! Chucky Train...boring.

Harry Potter world, minions, Shrek and the normal tour are closed everything else is open

Not all rides are available, minions, shrek etc are closed.

The whole park is open except Harry Potter World.
