it really is all about the attitude you come with. If you are predisposed to look for crowds, dirty bathroom, unhappy CM, bad service, you most def will find it
If you come with a plan that is flexible and realistic, and come with a positive attitude to have fun and enjoy the ride that is coming to WDW you will have a very different experience.
I see it all the times in the parks, you have the people that plan and bring binders and are go go go and have the negative attitude and they have a bad time
I see visitors that you can tell is their first time, basically after walking through the tapstiles is the first time they open a park map, they have no clue on fp or how it works and they have an awesome time
