I think the general theme of the thread, OP, is "None of us have any clue".
Pools may be open, they may not. Parks may open with the resorts, they may not. Sit-down options for meals may be available, and they may not. And so on. At the end of the day, the first people to go to the park are going to be the guinea pigs. And if the resorts are open in July, that means you. Since you said in your posts you wouldn't be happy with a trip that has limited offerings, you would probably be better off canceling the trip.
