How many rooms at Discounted S/D rate?

[Soccer Princess]

If I am booking at the Swan/Dolphin with the Teacher's Discount Rate can I book more than one more at that rate? We were looking at going on a family trip next December but would need 3-4 rooms probably.

I believe three is the limit, I've booked 2 at a time on two separate trips.
