EE is in a soft opening phase now and will remain so until the official opening on April 7.
What this means is: the ride is open a lot of the time. But it is not open all the time. There is no way of knowing if it will be open when you are there, unless you will be there on April 7 or later.
There are no restrictions to riding if it is open, as long as you meet the height and saety requirements, just like any other ride.
Have fun!
Bob
