Just came back from WDW and was a little disappointed in the way Vinylmation is handled. Each place does it differently.
They either only have the clear box of three (one place only had two) or they only bring up the mystery box at certain times or MAKE you choose from the mystery box first before the clear case or you can choose from whatever one you want.
It was a bit confusing. And each case had the same 6 or so vinylmations.
And the last time we were there, D Street had just opened, and every CM with pins was wearing vinylamtion pins. So this trip I had a few vinylmation pins and was very disappointed to see that EVERY CM was wearing a regular lanyard (apparently there was ONE CM with a vinyl only lanyard, but I didn't see him)
I managed to buy a few I needed and trade for a few i liked, but in general I was disappointed with how there seemed to be no set way of trading.
