Is there a teacher discount for our of state teachers?

There should be

I think so.

South Carolina certified teachers receive complimentary admission to the Aquarium. For a complimentary admission ticket, please bring proof of eligibility (certificate, teacher badge or recent paystub) to the gate. There is no need for teachers to reserve an entry time, but any guests in their party must buy tickets prior to their visit online.

Call them by phone

Yes, bring an ID
