Another vote for the location of Magnolia. As far as prettiness - we've stayed in all four mansion buildings and have enjoyed all four equally. People usuall want Magnolia due to it's proximity to the main pool and the east bus stop.
I'll be honest, though - the walk and the scenery are sooo relaxing here that I have never felt any additional walking was a burden. Instead I viewed it as another opportunity to see the ducks, squirrels,and rabbits.
Enjoy your stay !
