I actually really like all the hotels you listed as possibilities. But my two favorite "rooms for couples" that we've stayed in have been:
1) The garden cottage rooms at BWI. To us, these were heaven on earth.

We loved having the downstairs living room area, a second half bath down there, a guaranteed king bed, that fabulous jacuzzi tub, and the separate shower area...plus, the little garden in front or balcony (which our room had) was awesome too. It's so quiet where these rooms are, and ours was directly across from the quiet pool, which was also fantastic. We loved it so much we have a stay there coming up in February. Added bonus: I've seen these rooms pop up several times at 40% off rack rate.

We either got 35% or 40% off for our upcoming February stay...can't remember which off the top of my head. Plus, in my mind the CL offerings at BWI just can't be beat in terms of the quality of the food and the incomparable Chef Redgie.
2) The honeymoon rooms in the GF main building. These rooms have a jacuzzi tub too, but it's quite a bit smaller than the one in the garden cottages at BWI. We had an absolutely magical view of Cinderella Castle from our room (though I understand that's not guaranteed). The decor is so lovely at the GF, the lounge is gorgeous, and for me I've never felt as fancy as when I got to push that elevator button and ride up to my room right there in the main building, lol.
For us, given that EP is our favorite park (both for attractions and food!), we really love staying at BWI because it's an easy walk over there. Plus, there is quite a price jump between the garden cottages at BWI and the main building at GF, so we haven't pulled the trigger and booked GF main building recently...but we're planning to as a little gift to ourselves when our daughter starts college.
Good luck with your decision!
