I posted this on the newbie site but no one has responded so I thought I might try it here.. My DH and I are going Oct 25th to Nov 1st. 2 years ago when we were there, my DH bought the refillable plastic beer mug at the CS in EPCOT in Germany. I think it was like $11 and then you could get it refilled as many times as you want for like so much money. Does anyone know if he brings it with him they will refill it?

(I know they change the refillable mugs at the resorts every year so you can't reuse them from year to year.

I was actually thinking of bringing my old POFQ mugs to use and see what happens..what can they do? Just tell me no..)
Any help would be appreciated..
The souvenior beer stein is $11.50 and comes with your first mug of beer. You can then use that souvenior stein for refills, but the cost of the refill is the same as the cost of a "new" beer $7.00. So it's not a refillable mug in the true sense of the word, they will simply fill your stein instead of their plastic cup, but the cost is the same for either one. So, yes, he could bring it along if he wants to cart it around all day, but it's not going to save him any money over buying a beer without the mug. And other places that sell beer (or even soda) won't refill his stein.....he'll get a cup like everyone else and have to pour it in his stein himself, lol.
Refillable mugs are not useable in the parks....only at your resort. The posted policy says that it's for use at that resort until the end of your stay. So, you are not supposed to use it at a different resort and you are not supposed to bring them back the next visit.
The previous posters are correct....this thread could quickly turn ugly as people tell you that you are stealing from Disney by reusing your mug from a previous vacation, or by reusing your mug while you visit another resort to look around at the holiday decor (or whatever brought you to that other resort where you are not staying overnight).
However, human nature means that you'll have to decide for yourself whether you follow the rules as written and generally recognized as correct.....or whether you interpret those rules some other way, lol.
Just be prepared for a lot of flaming if you have your own interpretation.
Since I don't stay on site, I don't have to worry about what the rules say....so I skip the soda fountain and head straight for the pools. JUST KIDDING!! (for those not in the know, you can't use a pool if you aren't a guest of that resort....i.e. no pool hopping allowed, another big controversial topic here on DIS). At least I'm not bringing my short 5 year old along to the pools, he's in the parks on his "under 3 is free" ticket. (Yes, another controversial topic...and me joking again, since my kids are taller than me!).
