Last August, 3 week trip, poor wifi at AKL, BC, and GF pretty much at all times. At most times it was difficult to even login to email and transfer some pdfs. We had a few pockets of success, but really had to make do with Verizon/ATT 3g/LTE (which is also a bit overtaxed in WDW). I may be in the minority here, but I miss the $10 wired internet fee option. I liked being able to get a little business done pain free every few days. I understand the attraction of free internet, but if it isn't consistently usable, I would prefer the return of paid internet.
I watch the wifi threads because I am hoping that my experience was a fairly isolated occurrence or that it is getting better. I guess I'll find out next August.
