Yep that's my situation as well, but will miss it in January since we won't get there until the 18th. Oh well I will get to ride at some point.
I actually had originally booked my DW '17 vacation for 9/2-9/11 this past March. Well, a few weeks later, Disney announced that Splash was going down on the 28th of August for a refurb! Me being a huuuuge Splash freak and not having been to DW since 2008, I moved my trip to Aug 26-Sep 3 just so I could ride the heck out of Splash Mtn my first 2 days! LOL
