I understand you seem to be a big fan of the show. But you're looking at this without knowing what is actually happening on the ground. You don't know if everything is working together. You don't even know if everything in the show is actually working at all. In fact I'll even go further and say that everything isn't working together and that is the reason why the show isn't running. The issue is likely that the fountains and other effect are probably not all working in-sync, or maybe even issues with water pressure on some of the fountains.
This issue has probably cost them at least tens of, and could now be reaching over a hundred, Millions in repairs. Not to mention the lost revenue from the dinner/dessert packages and any ancillary revenue made from vendors selling WoC merch and other items right before the show.
Point is there can be lots of reason why WoC isn't running, least of which is "they don't want to bring it back". They want to bring it back, and once its ready it'll be back. And I'll even go out on a limb and predict that it'll be back by March for the traditional start of Spring Break, if not before.
