We split our stay between a honeymoon room at the GF (they are in the main building and come with concierge amenities) and a garden suite at the BWI. The WL also has honeymoon suites. We loved both of the rooms we stayed in, and each had its own advantages.
The GF has a wonderful location with the convenience of the monorail. The room being located in the main building is very convenient, and the Royal Palm Club concierge lounge is posh and elegant. The food offerings are upscale and extensive. The honeymoon rooms themselves come in two varieties. One of the types looks more like a regular room, but it has a king bed, sitting area, and small whirlpool tub. These rooms have views of the castle, though there may be palm trees partially obstructing the view. The other honeymoon rooms are turret honeymoon rooms. They have windows on several sides of the room and are hexagonal. They have varying views. These rooms are large and offer a large walk-in closet, wet bar area, sitting area, and regular bathroom. They are in the large turrets of the main building, so they don't have balconies. We stayed in the first type of room the first night, then the turret room the next few nights. We preferred the turret room, but it's really just a matter of personal preference.
The BWI has a great location within a 5 minute walk from Epcot, plus it is also a short boat ride or 25 minute walk to Disney-MGM Studios. The resort is all located in one building, but the entrance to the garden suites is outside from a courtyard. It is a bit of a hike (nearly completely inside) to get to the concierge lounge. The garden suites are actually two stories, and most feature a pretty garden area with a white picket fence. Most do not have balconies since they are set up as two story lofts. This room also has two bathrooms (one powder room downstairs and a huge master bath upstairs). The master bath has a huge marble shower, plus a HUGE jacuzzi tub. The lounge here is very intimate and luxurious with good food offerings, though not as extensive as the GF Royal Palm Club.
We honestly loved both rooms, and it's a tough call which one we liked better. I think that the BWI garden suite might win by a nose, but either is truly wonderful!
