I agree with the above about single rider lines. If so many people get in it that it is essentially useless, might as well make everyone go through the regular line. As a frequent solo traveler/single rider, I appreciate Universal having SR lines. I don't mind if groups of adults go in it if it is significantly shorter, but if it becomes overwhelmingly long it doesn't do anyone any good. I did see an issue with the SR line at FJ on Saturday, as a whole family with small children were in it, not understanding what it was.
