Ive been wondering about this, is there a best place?
I guess I wonder if theres one place where you can see everything without obstruction as its meant to be seen because when weve watched there always seems to be something in the way
Not really. There are trees all around the World Showcase Lagoon.
My main advice: find a spot you like upwind of the barges!
The best areas are near Japan, and Morocco. You can get an unobstructed view from there.
The UK and the US block the views if you are too close to them, so the best bet is to be as far away as possible.
Mexico and the cross between area are also good locations.
