Contact the hotel reception, they have a deal with the car park next door and will issue a pass for you so that you get a discounted rate
The deal the hotel has is with the car park right next door, not the one with the same name at the bottom of the road.
We paid £11 with the hotel's discount.
we didn't park in the novotel car park but in one of the private smaller car parks in the side road. It was a lot cheaper and the people were great. Not sure of the exact amount but think it was around £10
