I think few would argue that there isn't something special and different about putting in all the effort and having Pesach in your own home, or at a family members home and the feeling that comes with it.
If you choose this as your only way that you want to do Pesach then great!
But to argue that the other way is "wrong" because it's different seems silly to me.
What about the feeling about being with so many yidden and many times different types of yidden and all celebrating Yom Tov together?
What about your kids seeing other families doing things a little differently, dressed a little differently, singing a little differently and all celebrating together?
Like all things there are plus and minuses to all.
