The CMs are the biggest problem for WDW. There are a number of positions where it will be difficult, if not impossible, to keep CMs six feet away from guests.
Again, just to be clear, I'm not saying they won't be or shouldn't be reopening 7/11 (I plan to be there actually lol). I'm just trying to give some insight into the various factors TWDC has its eye on in regards to reopening plans. Anyone who thought they weren't going to be taking masks and social distancing seriously is in for a rude awakening. One thing I've heard consistently (but even more so now) is that Disney plans to be very firm with guests, which is a departure for them. But then again, their business doesn't depend on one party cutting line at It's a Small World, but it certainly does depend on no spike in cases being tied to their reopening.
