My thing is, if you have a time limit on when you can fill it, the mug is no longer really unlimited is it? I paid for the mug, I paid for unlimited drinks while I'm at my resort... not one serving every 5 minutes. I had a larger Disney cup (one of those tall ones with a straw) that I had purchased at the parks. I'd take my mug (that I legitimately paid for), fill it, dump it into my tall cup and then do it twice more to fill it. I was still at my resort and it was still during my length of stay... it just kept me from having to head back into the food court soaking wet from the pool or not being able to have a drink with the food I decided to take back to my room to eat (because the food court seating was packed).
I completely see the desire to prevent people from buying one mug and using it to satiate the thirst of their entire family, but they are essentially punishing those that use the system as it was designed (unlimited refills during your stay) because of those people who didn't. It's the one bad apple ruins the whole bunch concept...
Truthfully, if this does roll to each resort, I could see me no longer buying the mugs and instead just bringing water bottles, filling them at water fountains and using Crystal Light packets (or whatever) like we do in the parks. I think Disney may be setting themselves up to lose more money than they were from those abusing the drink stations to begin with.
I'm all for this. For those complaining about nickel and dining, if you pay for a mug, they aren't stopping you, they are only stopping you from stealing. The 5 minute limit is so you don't buy one mug for ten people, or use it to fill up your thermoses.
This ties in well as a promotion for the dining plan, since as of 2012 the mugs are included in the regular dining plan.
Never thought of trying those. I've seen them in the store, but never needed them here in NY. For FL, however...
