can you purchase pre-sale advance tickets with a gift card? And can you pick seats if purchasing at the theater instead of online?

I haven't bought them on site yet, but when using the app you can use your gift card.

Im not sure about that, to make sure you can call and ask some information. They have beautiful environment and gorgeous sets. Its beautiful theater.

Not sure about online you would have to try. You should be able to purchase at the counter.
