No, sorry I wasn't clear
We went to the Contemporary first and received the new mugs with our Dining Plan (2 black, 1 Pink and 1 Blue) and then we went over to ASMu and couldn't use them. My daughter was staying at ASMu and received hers with her Dining Plan and brought them to the CR from ASMu and used them at the Contemporary once and I saw many people with Orange, Green and other colors they do not sell at CR using them at the Cafe in the CR (they only sell black, blue and pink at CR) using them no problem so I was surprised when mine didn't work at ASMu when we moved over there considering they were the same style, just a different color.
Again, I believe the "length of stay" is for the resort, not the vacation, but they will accommodate you if you ask. Oh and to complicate things further for you lol a woman brought hers to the park and asked about filling it and they told her "those are for resorts only" and she said "can I use them at all the resorts?" and the cm said "yes, we do however sell souvenir cups here for all the parks" Again, I don't know...Disney needs to get on the same page lol.
PS, what is RFID? Thanks
