If all the rides are open, that would be great.
The only thing left to speculate would be operations hours. I've been crossing my fingers for 10:00am-8:00pm for the month of May. Once mid June hits, you could start doing Mon-Thurs: 10:00am-8:00pm and Fri-Sun: 10:00am-10:00pm.
In the normal world, we would be doing 10:00pm closing daily operation; but with a pandemic it's probably wise to save a few dollars. Fridays, Saturdays and Sundays could be your late closing hours. Remember; not everyone is going to stay the entire day. Some people will arrive at the park by 1:00pm or 2:00pm. I doubt with the pandemic that the water park will be open, so it's all games and rides.
So what will the park do with Flight of Fear? We've all speculated that it would be closed due to it being a enclosed building. There is a simple way to deal with this. I've mentioned this before. They could do a reverse queue. The exit would become the entrance. Once a full train is filled, the next group of people can enter the station. The returning train, then exits through the flying saucer, before the next group of people enter the station.
