I recommend that you stay at the AKL first and then transfer to GF for the remainder of your stay. That way you will be transferring from a resort with medium sized rooms and limited transportation options to one with large rooms and many transportation options. I wish that I had done that when I did my Poly/AKL split stay in September.
As for dress, nearly everyone that I saw at GF was casually dressed, meaning shorts, t-shirts, sandals. The guests at the GF certainly did not seem snooty.
We had the opposite experience (just to show how different people/times are) We won a trip from Kellogg's and they put us in GF for that portion of our trip, then me moved to AKL for the days I was paying for. Everyone in my family (3 DDs, DH, and me) all felt that GF (CMs and guests) were a bit too much for us. Mind you, I grew up in Europe and have travelled extensively and am NOT intimidated by snootiness, but when I'm at WDW on vacation, I have better things to do than be looked down upon b/c I was wearing denim shorts and hikers in the lobby. The check-in CM was probably what started us on the wrong foot...LORD, he was a snot! I was using traveller's checks and Kellogg's had sent us Disney Dollars and he acted like it was SUCH an imposition to put them on our room.

We were in Sago Cay and it was still a hike to the monorail (although that was nice for the MK) Getting anywhere else was still pretty much a bus.
By comparison, when we switched resorts and walked into the AKL lobby, everyone in my family visibly relaxed and DH looked at me and said, "Why couldn't we have stayed HERE the whole time???" The GF had really affected how he looked at WDW and NOT in a favorable light! Our stay at AKL was so nice that we returned a year later for 10 days there and it is by far, our favorite place to stay. We are value-oriented, so for us, this is the deluxe resort with the most value: pool, activities, restaurants, savannas.
I think it really depends on your personality. Are you going to be put off by the frou-frou (as DH calls it) of GF? Are you more down-to-earth? Then you will probably feel your vacation dollars are better spent at AKL and then spend some time dining or visiting GF. Do you like Victoriana? Is there something at GF you feel you won't get anywhere else? Then give it a go. You won't know until you try.
