Oh for goodness sake, do people really think that Tink and the other fairies make the magic overnight, lol? Of course there are going to be things that are under renovation at one of the slowest times of year. Of course things need repair, maintenance, refurbishment. It's not like they closed the park, for heaven's sake! Some people really need to relax about stuff like this.
I'm quite sure there is a lot of magic, as always. You just have to be open to it and realize that a few "under construction" type of things won't ruin a vacation.
