Sounds like a great list of things to keep in mind. I totally agree with you on the unassigned tables, my friend's wedding was like that and it was just really confusing.
I vote for trying the GF, we LOVED AKL until we stayed at the GF, and that is our new favorite. We still do love AKL, but being on the monorail is great and at the GF was the first time I've stayed at a Disney resort and really wanted to spend more time at the resort than the parks!
