Thanks Have just booked via link you posted 2 comments above, for April/May.
Thank you OP. The discount is applied using the link you posted about 30 minutes ago. I was able to book for Easter.
The URL I saved on this offer does not seem to be working, I will edit but I 12% offer is available for next week http://bookings.gatwickairport.com/EN/default.aspx?a=AffWin&av=Affiliates&pc=VCJAN15&utm_source=AffWin&utm_medium=Affiliates&utm_campaign=Parking&awc=3498_1420560150_d481efc64fdc01b96c373cfad958d5cf&a=AffWin&av=Affiliates&utm_source=AffWin&utm_medium=Affiliates&utm_campaign=Parking&awc=3498_1421340625_c130366fe2cfdae9b24555f9ac0250d8
Cancel and use the 10% off not getting the 12%
I booked through them at the beginning of the week and it was actually less without the 12% off?
