Well, I can't speak for Broadway Bares, but I went to Stars in the Alley and I'm 5'0". Thank God I got there decently early, I was in like the third line of people standing and even then only saw between people's heads. Two or three rows back and I wouldn't have seen anything. I get your best bet is to get there as early as possible. But for the record, I really think they should have a separate midget-like area for people like us.
And OMG, one of my friends from HS's nickname for me was Oompa Loompa!
"If there was a Mount Rushmore for Broadway scores, "West Side Story" would be front and center. It snaps, it crackles it pops! It surges with a roar, its energy and sheer life undiminished by the years" - NYPost reviewer Elisabeth Vincentelli
