It was closed for a long time to make some changes. Then it opened with the holiday version. It closed again to take all that stuff down and I don't know when it will re-open and we will get to see the new changes they made.
The big question is - what changes are made that we did not see in IASW Holiday. It's quite possible when those walls come down, we will see a Small World that is very different with extra little animatronics of Disney characters throughout. Nothing has been released from Disney to confirm or deny if this has indeed been done. We'll find out in 3 weeks.
