We stayed in Garden Suite 1201 (which I had requested since it's closest to the stairs). PP gave you a good description of the layout (downstairs seating area with a sectional, wet bar with a little fridge, desk, TV, and 1/2 bath; upstairs king bed and large bathroom). The pictures on Disney's website really don't do the room justice. There's pretty art work throughout, nice furniture, and the bathroom finishes are lovely.
As another PP mentioned, there is a "secret staircase" in the alcove next to Room 1201 where the ice machine is (I'll post a pic of 1201 below- you can see part of the alcove on the left hand side). It's not the nicest staircase, but it gave us quick access to the lounge on the 4th floor. We were also close to the quiet pool.
DH and I are picky when it comes to hotels for our kid-free weekends away, but the Garden Suite really delivered. We've been thinking about changing our vacation plans for this year so that we can stay at BWI in a Garden Suite again!
The only annoyance was getting from the Garden Suite to the front of the hotel. It's not a direct route, but given how beautiful and quiet the Garden Suite area is, it was a fine tradeoff.
