Hi
We always stay in a villa on Emerald Island.
I can't reccommend any of the other complexs because we haven't tried them, but that's always because we are statisfied at Emerald Island.
We usually hire a 4 bed room villa(sleeps 10 - sofa bed too), 2 with en-suite, pool, hot tub, pool table in garage and Play station. Not that we get much time to play with the play station lol.
We find the convience of a 8-10 minute drive to WDW great and lots of shops on the 192.
Good luck and happy planning
