I saw an article yesterday: http://travel.usatoday.com/alliance/destinations/mouseplanet/post/2011/07/Walt-Disney-World-Resort-Update/178366/1
Basically they were talking about how the new mug chips will be tested at All Star Resorts soon. They talked about this a bit in the article..but they were saying how the dispensers would only work if the chip was present. What about the paper cups? Apparently there was a rumor (according to this article) that paper cups would ALSO have the chip. Holy waste of money. This is just speculation though but it's a good point..if the dispensers will only work if the chip is present how are other people with regular cups going to fill up? And what's to differentiate between a paper cup without a chip and a mug without a chip?
I'll be interested in hearing about guests experiences with this mugs & chips.
But seriously, if the drink thieves are causing that much of a problem--why not just do away with mugs then? This is all getting a little ridiculous. But that's just my opinion.
