this is incredibly inaccurate from my experience during the week. I went to AK during the week and got there around 1. I rode Everest 5 times, Dinosaur 3, FOP + NRJ. They closed at 6.Also, if you're not at the park at exactly rope drop, you can forget about riding any marquee attraction.
Went to MK during the week and got there around 11. We rode 7DMT, Pooh, BTMR, POTC, Space, and HM while still being able to walk and enjoy the park.
