Hi! Another view...
My first trip to WDW was at the All Star Sports, second trip was at the GF. What a difference! I loved knowing that when I left the parks, I was coming home to a fairytale castle

I think that the GF is just beautiful, and always get that feeling of "coming home" when I get there. We went on our wedding planning trip last month and stayed at the CSR. It was okay, but we actually ended up spending much more time just wandering around the GF. Our favorite restaurants are there; we love the shops; we love the lobby; we love the orchestra; we love quiet walks along the beach; we love the view of the castle and the Wedding Pavilion. Staying at a moderate after having been at the GF, I really missed the peace and quiet of sitting on our own balcony. It's probably what I enjoy most about our room at the GF, so for us, it is definitely worth the extra money to have all of these wonderful feelings while we're vacationing at WDW.
For us, it has less to do with the "prestige" and more with just being absolutely in love with the resort itself. Also, when we stayed at the AS Sports, there were kids everywhere. We saw significantly fewer at the GF, which is a plus for us. We're both the kind of people who are bothered by small children running dripping wet in bathing suits through the beautiful GF lobby - seems like sacrilege!

Not that we complain; their parents are paying the room price, and I am sure not everyone has the same reverence for the GF that we do.
Anyway, the point is that we pay the money so that we can stay in the most magical place in the world, to us, so we find the price well worth it.
Cheers!
