Ok, so recently my wife and I were at MK, and Splash Mountain was closed. The water was drained and the crew appeared to be power washing the canals. It was cold so we figured they were taking advantage of the cold weather and odds of nobody riding in freezing to almost freezing weather to get the canals cleaned.
However, we returned yesterday, and Splash was still down. It was a nice day, so I went to find out what was up. The CM in front of the entrance said Splash is down for refurb until some time in March. Just thought I'd let you all know.
The water around the castle is all drained too. Not sure what that is about though.
