For as rightly praised as DLP is for its immaculate attention to detail and stunning design, there's one thing it fails to do as good as The Magic Kingdom did, and that's where and how it parks its riverboat for maintanance.
At Disneyland in California, there's a bend in the river where the Mark Twain can be docked for work. It's uncovered and is used occasionally for that purpose, but is largely inconspicuous. Walt didn't like it, but during initial construction of the park it was considered the best overall solution.
Shown above is my picture taken of what's left of DLP's Mark twain, in a similar dock, but one that is fully enclosed to protect it from the harsher elements of the local climate.
This works in a practical sense, but as you can see it not only looks unflattering, but this big structure (sitting next to the the huge Frontierland Theater) dwarfs Becon Joe's cabin next to it and kind of spoils the illusion of this being the untamed wilderness beyond Thunder Mesa.
Magic Kingdom over engineering a solution to Disneyland's problem is another example of how WED went the extra mile for the sake of show and should be considered in the same vein as the Utilidors for that reason. Having to pull the Liberty Belle down a long river to get to the Seven Seas Lagoon, then cross that lagoon to get to Bay Lake where the actual dry dock was is incredible. Both in that such effort had to be made for routine fixes, but also that WED wanted to preserve the aesthetics of Seven Seas Lagoon AND Bay Lake too! Three bodies of guest facing water that were considered on stage, part of the show and needing to look as natural and picturesque as possible. And they succeeded.
