we will have Disney refillable mugs
It's not sold on the cruise, only WDWAre you referring to the resort mugs or something different they sell on the cruise line?
I thought so. The wife was asking if we should bring ours and I wasn't sure if it were a good idea or not because I don't want to give the impression we're drinking and trying to sneak alcohol around the ship.
Plenty of people bring various refillable mugs - from WDW or something else - to use at the drink station. As PP said, just make sure to use a paper cup to transfer your drink in order to avoid contact between your refillable mug and the drink station for hygienic reasons.
They even sell Tervis tumblers with DCL designs on the ship, they certainly won't think you are using your mugs to sneak alcohol around (even though I am sure there are a few people who do, but really what is keeping you from carrying your paper cup with coke to your room and add some rum to it).
I agree. It is very common to see people carrying around their own cups, and it's often because the disposable cups DCL supplies are tiny, not because there is alcohol in them.
We hardly ever drink soft drinks so I can't really see that big of a need of them anyway, but always nice to know.
You might still want to use larger cups of your own for water, unless you plan to bring bottled water on board.
My initial plan was to bring insulated water bottles that I use when cycling. They hold about 20 ounces (unless filled with ice) which I still will probably bring as well. But I'm sure the wife can dig into our cabinet to bring one of her 1,593 sorority party cups from her college days.

You can get ice from your room host and fill up in your room. All the water onboard is processed the same way, whether from the drink station, or from the tap in your room. Also the same water for making the ice.I fill an insulated bottle with ice and water from the station to take back down to the stateroom
