Hi Jbock,
I'll start out prefacing this by saying I never have stayed in the Garden Wing, though last year the prices in "the tower" actually came down enough for us to try a few nights. I had always wanted to stay there since being a kid many decades ago. It was everything I thought it would be and more. Though we were on the lake side, as soon as we opened our door to the hall we could see the MK, Cinderella's castle, Space Mountain etc. Also being able to watch the monorail run through was just such a joy, not to mention going up to the roof to watch the fireworks at night. We finished that trip, our first split stay, with several nights at the Yacht club.
The reason I say all that is I'm just not sure I would get that same "feeling" in the Garden wing, which is, I'm assuming you know, the smaller buildings off to the side, on the opposite side of the Magic Kingdom. I have heard the rooms are just the same, very nice, but you do have an additional short walk to get to the tower for meals and shops, plus you need to pass through the main tower to get to the bus stop or walking path to Magic Kingdom.
Personally, I think I'd prefer a different deluxe if the price is the same for the garden wing. If I could get a tower room for the same, then a no brainer.
My two cents
