Congrats on your upcoming wedding.

I have to agree with everyone who has stated the Grand is perfect for a honeymoon. The resort is gorgeous, the service is wonderful and the whole feel there is romantic. We have stayed in all room categories and loved each one, so I wouldn't hesitate to recommend the garden view rooms. Nearly all have very pretty views of the marina or courtyard pool and outer buildings. There are a few in Sago Cay that look out the back over landscaping towards the monorail.
I have not stayed at BLT, but have visited and it doesn't feel romantic to me at all - nice, contemporary, but not especially romantic.
I do like the Yacht Club, and agree with those who suggest it for an Epcot resort. Beach Club is my favorite in that area, but the Yacht would be more quiet and romantic for honeymooners.
There are several recent reports from first-time guests to the GF who fell in love with the resort, here is one:

Good luck with your choice, it's always tough to pick just one.
