Early arrivals are out of the question in any scenario because of safety issues. Ideally they would keep BG in place of standby lines. I would suggest FP for resort only guests for a limited percentage of the availability at the 60 day mark. I would also limit in state AP to ride once per week to open up availability. Out of state AP would get 6 rides per year and could use however they liked. I would then offer BG twice per day for the remaining availability in order to give day guests a chance to ride day of, but not limited to park opening. The only real operational hurdles I see are the 2nd BG during the day. That would take some trial and errorDon't care about Disneyland. Both resorts operate uniquely and will require specific rules.
Security is a consideration. They are investing millions in crowd control and they might have to just accept this as part of operating costs.
The new E+ attractions (as I call them) are changing the dynamics. Systems that worked in the past might have to be rethought. The 50th anniversary will bring further challenges.
i came up with my best thoughts and welcome any critique. I always appreciate critics that post a better solution. And look forward to your ideas.
PS- my plan B is a pure lottery the day before. If you win, you are unable to reenter a new lottery for 7 days. (Per attraction) No exceptions.
Only one lottery per guest/party each day.
