I would suggest AKL or WL. Both are very quiet, intimate resorts, but cheaper than the Poly or GF. AKL has a great spa, plus the views of the animals are amazing (even if you get a standard room, there are plenty of viewing areas). There's a firepit to sit around (though if you go in the summer I guess that wouldn't matter) and they have great activities, like night viewing of animals, etc. Also, both restaurants there are very good and the pool is really well themed. We're spending part of our honeymoon there since after we stayed there once I fell in love with the resort.
I've never stayed at the WL, though I want to, but have visited and it's beautiful as well. I've heard great things about the restaurants, the outside grounds are great, plus you have the boatride to MK. Although you can see the monorail and MK from parts of the resort, you really feel isolated and like you're in the woods.
If they're still more money than you can spend, for moderates I would suggest POFQ if it will be open when you're planning to go. We planned to stay there in October but it was closed for rehab, but we visited in Jan and Feb and it looked like a great resort. Much smaller than the other mods so nothing was far away from the pool, buses, food court, etc. POR is supposed to be very nice too, but I've only seen it from the bus so I can't say much about it.
Congrats and have a great honeymoon!
