TWO
Just saw this deal when trying to book for 12 days at the Intl multi storey car park (what a timing!)
Valid until 20 July or until sold out. I booked mine on 13 July 7.50pm Brisbane time.
Use the code "TWO" in https://parking.bne.com.au/ (below the start and end dates)
Thanks OP.
I just booked parking for 11 days in September, saved me $70, thank you.
