At one time, some folks had lifetime passes to DL. You could get into the park for free and then buy your tickets for the individual rides. I don't know how they worked it out once all of your rides were paid for with admission.
Off the mug debate - but I thought I heard that if you brought back your individual ride tickets they would "pro-rate" them towards your park hoppers or whatever other tickets you would be buying.
I can't imagine they would be worth much now-a-days, so it may be better to keep them as souvenirs.
