Do you mean express pass plus.....
If you did get the express pass plus, you get express access to all (or most ) of the attractions to the park you bought the express ticket for. This means that you go to the express line without waiting first. It is limited to one ticket per person per attraction. So you can only go express once per ride.
Regular express (non-plus) you have to wait about an hour before you go in the express line
Feel free to ask any more questions
