We stayed in the honeymoon room concierge level at the GF.
I LOVED the GF for a wedding, but did not think the Honeymoon Room was worth it.
(Pros and Cons specifically for GF Honeymoon Concierge)
Pros-the view was AMAZING
Cons-
-it's not in the same area as the concierge lounge. We had to take an elevator and then walk down a corridor to get to it.
-we were too busy to go out of our way that distance to take advantage of all the snacks
-the jacuzzi tub is too small for two people
-the room is the same size as the regular GF rooms
My parents, on the other hand stayed in a Deluxe Concierge at the GF. The room was twice as large, and they were right next to the concierge lounge. Of course, they didn't have the jacuzzi tub or the castle view, but they still had a gorgeous view of the grounds, plus a huge sitting area.
Personally, my parents' room would have been a perfect splurge for the day or two leading up to the wedding. It would have been nice to have that space to get ready in, plus the convenience.
But, for the honeymoon, I think 1BR DVC is nicer (with a larger jacuzzi tub).
I have heard that the Poly concierge is an AWESOME, well-worth-it splurge, though.
