XANADU - when you come out of the theater, make a left. It'll be a gate and there will be barricades set up.
IN THE HEIGHTS - make a left when you come out of the theater. There'll be a step up to a door that says "stage door". Wait there.
LEGALLY BLONDE - make a right coming out of the theater and curl around the block (go down 47th street). You'll see the stage door straight ahead.
THE LITTLE MERMAID: Make a right when you go out of the theater. You'll see a door plastered with a poster, and on the top it will say "Lunt Fontanne Stage Door".
YOUNG FRANKENSTEIN: Exit the theater on the 43rd Street side, then make a left. There'll be a big glass door that says Hilton Theater Stage Door.
THE COLOR PURPLE: When exiting the theater, make a left and curl around the block. You should see some barricades.
As for Megan/Sutton/Roger, I'm pretty sure they don't come out during matinees. Some of them use another exit if they have to go out at all. It'd be better to catch them after an evening show, if they do come out the stage door.
Have a great time!
