Refillable mugs?

[magicman]

A few years ago, we bought refillable mugs at CBR. This year, we decided to stay at a different resort and we picked POR for our stay. Can we use the same refillable mugs this year at POR?

You cannot use mugs from different resorts unless they are "sister" resorts, such as the All Stars, or POR and POFQ.
