you can order them online, but it's a little tricky. you go to the Universal Orlando website- Click on the Tickets and Vacations, Next click on Vacation Packages There is a little section on the rights hand side where is says customize your vacation you enter your departure day as the day you want the tickets for and hit the little tickets only button and hit enter On the next screen you hit go and a list of tickets you can buy comes up It will have the express passes as date specific with the price for that date( not sure how far ahead of time this will allow) I ordered mine this way for May and they sent me an email making sure I knew you have to have regular addmission passes and that the express passes were date specifc before they processed the order. Hope this helps
