The single riders line is not clearly marked. It is initially the same line as Fast Pass. When you get to EE, go up to the attendant taking the FastPassess and tell him/her you would like to go in the single riders line. He/she will give you a ticket that reads 'Single Rider'. You will walk through the Fast Pass line, and then you will see a sign w/ an attendant standing by it that says 'Single Rider'. Give you pass to them and then you will join the Single Riders line. It really goes by quite fast, and a great way to ride if you do not want to wait for an hour, or are by yourself.
