I know for THE COLOR PURPLE and LEGALLY BLONDE its reccomended to get there around 7 or 7:30 in the morning if you want tickets
Wish SPRING AWAKENING, I think its about 8 or 8:30
XANADU doesnt have rush, but has onstage seats. Not sure if you could get 5 last minute, though.
SPELLING BEE, A CHORUS LINE, THE YEAR OF MAGICAL THINKING, and probably another show or two have rush. SPELLING BEE is supposed to be somewhat difficult, but the other 2 are supposed to be pretty easy.
Have fun at whatever you end up seeing :)
