OK regardless of if in general it makes no sense to WDW people, the pin SERIES is based off of DLR hence the titling of the pin as Mark Twain Riverboat instead of Liberty Bell. So therefore it would make sense to include Fantasmic.
Also VMK is not based off of any Disney park in particular; however there are many DL exclusive aspects: Alice in Wonderland dark ride, Matterhorn, NOS. The castle though, is from Disneyland Paris. Nothing that is in VMK really stands out as WDW exclusive (then again.. MK doesnt have much that is MK exclusive
)
