I assume by MFSM you mean Smuggler’s Run- the single rider sees none of the queue, not even the preshow. You go down a themed hall and up a staircase and are merged in the lounge. Fyi- if the line is much longer than past the top turn in the steps, you’re looking at 20+ mn. With fp being added to SR, the standby line is probably going to be double what it has been recently. During the night shows will probably be the shortest wait.
