You've rightly chosen to arrive by 7. Oct and early Dec 2018 trip both had AK opening well before the stated opening/ EMH times (also DHS doing the same). At AK, I was usually getting off FOP at stated opening time & at DHS I rode both RNR & ToT before stated opening time. Each day, I heard people inquiring why the app showed a wait time for rides when the parks weren't even open yet? I would just smile and say 'because the park IS open.'. I'm sure not too many were happy to find out they did NOT make it to rope drop.
