The question mark is really whether or not the Night King is capable of getting past the wall without Danys dragon. If he isnt, then all of this is mostly moot since the Walker are stuck behind the wall. Dany can take her time. But if it's possible somehow for them to past the wall, then how things ended up might be for the best. Even if Dany does take Kings Landing quickly, she might not have committed ALL her forces to the North since again she didn't necessarily take the threat that seriously until she saw it with her own eyes.
