"Drink of the Day" - question

[Sack66]

It's been mentioned that if you bring back your "drink of the day" cup, you may get a discount on a refill of the "DOTD". However, I don't know which cup this is and if this is completely accurate. I cruised in Oct05 and, believe me, I have plenty "DOTD" cups and I also have a "glass" beer mug but I don't know which one I should pack (if any) that would fall in this category of "refillable". Does anyone know of this?

Thanks...
