My family frequents
Disneyland about twice a year.
Reading how some people plan amazes me sometimes. We don't plan our days out and we will never wait in line first thing for a fast pass. We have to young kids (6 & 2) and can't wait in long lines or wait for a show for very long.
We feel like we get to do most things anyway. We don't have the best spot for Fantasmic, we don't stake out a spot for fireworks, etc... but we still get to enjoy them. We used Single Rider Line for RSR and it was fine.
I think for some people planning is part of the fun and adds to their experience, but for us, we just like to enjoy being there and do rides when we feel like it, not when we're supposed to.
We usually go during the week (Sun-Fri) on off peak times so we don't have to plan things out like some people do. I also saw WOC once and haven't felt the need to do it again. I like Fantasmic way better.
I still enjoy Disneyland, but I don't think I would enjoy it as much if I had to adhere to a strict schedule like some people do. For me, I think it would take some fun out of it.
