I would say it is worth it, but I like to spend my money on good food and Disney. Went a couple tomes as a small party and it was wonderful. After our wedding in 1990 the wedding party went there for brunch the next day (unfortunately my bride and I were already on a plane for WDW). Family said brunch was good also.
I want to be one of the envied on the balcony! 
There are 4 adult and 7 kids but I would have no issue putting the little ones in the GCV "daycare" during our meal if just the adults could go. At all. I have family in the area too if all else failed.
Cool doing WDW for your honeymoon.
Now I am all excited and watch it not work out. 
Go have a wonderful time.
