Mickey Straw

I don't think anyone thinks you shouldn't be able to vacation in a way that works for you ..... within the parameters set by the destination. We all have stuff we deal with, my family sure does. But we all have to work within what Disney is offering. We also have to follow their rules. Entering the AK last week we were told to dispose of our straw (I forgot DS still had his cup from breakfast) which we promptly did. If Disney truly wants to send the message that this is part of their plan for "environmental stewardship" they may very well ban plastic straws from property altogether. They can do that because there are other options.
