Hi all, I Organised parking for the concert and you dont need to specify the car that you will be parking there. I'm happy to pay the additional booking fee as it saves struggling to find a park and you dont have to line up to pay after the concert - those lines are hectic!!
Heres a link to the parking options available. You can also call ticketek and reserve a handicapped space if required - there are only 179 of these available though in P1 and they will give you a discount off the parking. They also do reservations for minibuses! Phone 132 849.
