Sorry to say we had horrebdous problems with the Burger King BOGOF offer that I lost a little faith in the Universal system for showing when passes expire!
Here is a little summary of what happened -
We first went with the BK BOGOF offer in Oct 2004, and when we got the photocard AP they put an expiry date on for the day after we got them made up! Unknown to us as there is no expiry date shown on the pass. Hence the following day we couldn't enter the parks and it took ages to get guest services to put it right. Then upon our return last June (2005) as the 'computers' had been upgraded, since our visit in Oct 2004, our passes once again said they had expired and the date was the day after we had them activated the previous October, after another wait and being told we couldn't possibly of had the 2 for 1 offer it all got sorted but was a stressful time and wasted valuable park time!!
But this had made me think in future that I will take copies of emails, confirmation of purchase etc with me.
BTW know of other people who reattended only to be told their passes were one year and had expired!
