The understanding I have is the credits will be permanent for the games (fireworks, pirates and jungle cruise). The daily host events they have numerous people have asked will the credits stay, and for a long time people where receiving conflicting answers. My understanding as of the other day is these credits will stay long term. Now don't get me wrong, Just like blue furniture, valentines day, and some other items, game changes, etc...Virtual Magic Kingdom can make changes at any point and time without communicating that information to vmk members. The credits will stay, but who knows what they may do down the line.
