Despite currently being closed through November 16th, 2017, Splash Mountain at the Magic Kingdom will be closing again for refurbishment in early 2018.
The second refurbishment will take place January 8th through February 1st, 2018. The reasoning for this second closure is unknown, but may be related to some leftover work that can’t be completed during this ongoing refurbishment. The Magic Kingdom would want the attraction open again for the busy holiday season, thus why it will still reopening in November but going down once more in January.
