Yes, I agree with you. There's a lot of pent up demand, and there's a large segment of the theme park vacation community that hasn't really been adversely affected economically by this crisis.
There's lots of money on the sideline that people are eager to spend, and a thirst to get back to normal vacations. Once people feel it's safe, and theme parks get back to normal, or almost normal, operations, the floodgates will open.
I think you're timeline is right on, barring any unforeseen happenings.
