I hardly post (actually never) but I just figured I might add a like something here.
You see I`m from South America and people here (actually the entire southern hemisphere) have their summer vacations in December and January.
Parents will more often than not use this time of the year to take their kids and I feel bad for them that they haven`t been able to ride Splash Mountain since 2006 or 2007, which is when I believe the annual January refurbs started (please let me know if I`m wrong).
I went to WDW in January 2013 and I was bummed that SM was in refurb, but I knew it was long overdue and was glad it was happening. However, it sure wasn`t a slow month. There were queues over 40 minutes in virtually everything. In every park.
Prior to that trip my last time January trip was in 2004. SM was open and, as mentioned here, it was a walk on. Actually, everything other than TT, PPF, and Pooh were walk-ons. And maintenance was fine. So although I am glad that everything is being taken care of, I wonder why all of a sudden there is a need for such long maintenances. A long time ago maintenance and hygiene were far superior than what they are today and it didn`t require closing 20% of the park.
