Instructions:Only £19.95 for up to 2 weeks on-site parking.
Book online or call 0191 214 4341 and quote "NT". Terms and Conditions say "bookings made within August only". We are off on holiday next week, and I've booked it online, no problems. Don't know if it will work for bookings made in August if the departure is later. Would have thought so though.
£79.99 without the code when comparing price via airport parking comparison site.
