i have not bought my AP just yet,
but i wll be getting 2 fantasy passes.
i also have a 1 day hopper pass which i got as part of a deal with P&O which i am hoping to claim back against the cost of the AP's.
With your fantasy AP you can park for free in the main car park
Check to see if your ticket has a value printed on it. Experience from others suggests that if it does not have a monetary value you'll probably not get the deduction off the AP.
We had the price of the first days parking refunded off the price of the AP's when we paid at the AP office. This was over a year ago and things may have changed but it is worth a try - just keep the parking receipt.
