I had zero interest in the Polynesian when we reseached our first vacation. I didn't even entertain the thought or open threads about it. I don't know why, a couple reasons, first, we had been to Hawaii for our honeymoon and I thought "fake" Hawaii would be cheesy. I also felt it would be too old, which I know is completely stupid because some of th greatest hotels in the country are decades old.
Anyway, on our first trip we went out for dinner at the California Grill, and left our dd at the Neverland Club, since it was right on the monorail and we'd heard it was the best kid's club. Anyway, we were only there a short time but my family fell hard for the Polynesian. The first thing my husband demanded when we went to the GCH was "Why aren't we staying here?" (We had a very nice place at BWV, by the way.) To him this was the essence of Disney--- on the monrail, full immersion theming... and something about those early resorts, the Poly and the CR, you just feel Walt a little bit, even though they were completed years after his death. My husband is sort of old school- he loves WDW, but I think he thinks MK, the monorail, CR and the Poly are all the "real" DisneyWorld... everything else is just an add-on!
Anyway, 3 years later we stayed there for the first time; I resisted a little because of the cost but between my husband wanting to stay there and my dd wanting to go down a volcano slide, I was overruled. We weren't disappointed. It was a very lovely, special, laid back place. I highly recommend it.
