I just saw a picture somewhere (Allears?) and they are pretty generic. I was shocked to find out that each resort doesn't have its own any more. The mugs make great souvies, and I loved having AKL mugs, and Poly mugs, and ASSp mugs, etc.
We didn't get mugs at Boardwalk tho. They were seriously lacking in resort merchandise of any kind!
Actually, the mugs are $12.49 each...at least the mugs being sold at the Mara at AKL.
One funny thing about the Mara, the signs there state that the mugs are only good for refills AT the Mara only.
