The paper straws with a coke are horrible. It fizzes in the paper, making every sip taste like you're drinking the foam from a top of a freshly poured glass. I actually don't even use straws in every day life at restaurants, but Disney is one of the few places I do since I need a lid while I'm on the go. I'm all for reducing waste, but if Disney really wanted to do that, I think a better solution would be offering reusable straws at a small cost, or even better, taking a page from the Universal (and pretty much every other theme park on the planet) playbook and selling refillable mugs/cups. I rarely actually pay the $4 for a coke in Disney, but if they sold these for say $30, I'd be all over it.
