Went last year but didn't get a mug. I have a few ????s about them. I see the mugs tend to bring some controversy and I don't mean to stir any up here. I really want to know.
1. If I buy my mug at POR can I only refill it there???
2. Can these be refilled at the parks???
3. Is there a way to distinguish 1 mug from another??? (Heaven forbid my DD12 drink out of her brother's mug---ewwww

)
4. Can you buy them at the parks???
5. Can you use them at the water parks??? ( I think you need a bar code thing at the waterparks.
Thank you for all you help.
