I've seen Daddy Long Legs from the 1st, 4th or so, and rear orchestra, and it really doesn't make much of a difference. The theater is so small, all seats are good. It also doesn't matter if you're on the side or in the center.
I think you can probably just show up and save the online fees. The last time I saw it was on a Saturday evening, and even though it was 20for20 I had no problem getting a ticket 20 minutes before curtain.
