I agree with the fact that "expected" doesn't mean "guaranteed", if it is not stated on the event you're attending.
When you book PPO breakfast, you know you're only paying for the actual breakfast at the restaurant of your choice. You know the prices and you're still making it your choice. Low-ppl park photos, and earlier entry to the park to get to your restaurant are a given for you to get there. Nothing else. It doesn't say anything about letting you in rides before opening, or FP+ included for any ride.
I doubt this trend will affect BOG Breakfast in any way, as you usually have ALL breakfast spots fully booked (both PPO and after opening).
I'm guessing that now, having an actual event for pre-opening rides, as it is EMM, then they will stop allowing this to happen to encourage EMM assistance as someone mentioned.
So, #1 rule of WDW, do NOT expect more than what you're offered. IF you do get more, great, but if you don't then remember what you were offered in the first place.
