Mean Girls Sunday Evening

Hi! I'm planning a weekend getaway to NYC on May/June, and the show I want to see the most is Mean Girls. I just realized they now have a Sunday evening performance instead of the Wednesday matinee, and it fits perfectly in my schedule. I just want to ask, as an "extra" performance, do you think the principal roles are played by understudies in the Sunday evening performance? I really want to catch the original cast! Thanks!

When schools let out they will change the schedule back to Wednesday matinees, and there will be only one show on Sunday at 3pm. After March you won't find the majority of the original cast there either.
