Is there any rhyme or reason to how much time must elapse between the time you get a fast pass and when you can get the next one? And is there any way of knowing what that time will be before you pull a fast pass? For instance, if I go at 9am to get a fast pass for Test Track and the return time is 8 pm, when am I likely to be able to get a fast pass for another attraction? I'd hate to get the first fast pass and not be able to get another for the rest of the day. I know it used to be you couldn't get a new one until the return time for the first one, but I believe that has changed, right?
