Disney typically starts many refurbishments in January, after the large holiday crowds have subsided. This is especially true of water based rides, as they tend to be much less popular during this cooler time of year. Splash Mountain will be down for a few months this year. This dry canal is in the area right after the big drop. I took this photo today while enjoying a very cold morning at the Magic Kingdom. The temperature was in the. 30s, so it is quite possible that Splash Mountain would have been closed even if it wasn't down for a major refurbishment!
