Can you get coffee or tea if you are on the refillable mug program or is it just soft drinks?
Yes, you can get coffee, and I belief tea as well. What you can’t get is a cup of milk - which was frustrating as my kids don’t drink much soda.
I’m scared to say this, but on wdw prep school I just read that get could be refilled at any resort? Is this a recent change?
Yes, I believe they changed they policy and that is possible now, but I don’t know for sure.
Yes, you can use them at any resort. I did a resort tour and took my mug with me.
Yes new RFID muga can be filled at any resort. You are paying for unlimited refills at the resorts for your stay. I always filled my mug with ice water in the morning and then threw it in my backpack, just in case.
You can get iced or hot tea. That’s all I drink.
