You can not stay in the mainbuilding only if you have a CC room or a suite.
And as we have never stayed in CC or a suite yet we have only stayed at the West Wing (2 times) and the East Wing (2 times).
This was our view during the first stay September 2004 (East Wing)
During the second stay (May 2005) we had a view to the RER station. (East Wing)
During the third stay we had a room at the West Wing to Fantasia Gardens but as the trees were quite high we could almost see nothing. (Only if we leand out of the window) But therefore we had a balcony during this stay.
And the best view we had during our last trip in June 2008 when we had a room in the East Wing.
We don't have a favourie Wing. You can have great rooms in both wings and you can have not-so-great rooms in both wings. It is worth to ask for a room in the upper floors. Or you ask for a room in the ground floor and then you can have a kind of private garden like in the picture here:
