This of course is a very very subjective question. I have only stayed at GF once, a standard room (going to GF concierge this time becasue FTP made it affordable), and only been one time to the Polynesian, passing through for the dinner show, and for me personally the GF was more what I enjoy and feel at home with, though of course I enjoyed the dinner show and atmosphere at the polynesian (I suppose for me it was a nice place to visit but would not want to live there), but just glance through the posts below, and you will find many many adherents who swear by one or the other, some who swear by both. I would I suppose ask which fits your fantasy best, disney versions of exotic beaches and leis and tiki huts, or high victorian and emersion in disney's version of rubbing elbows with the vanderbilts and rockafellers (or mary poppins for that matter) . . . for my personal comfort I loved the feel of the grand in GF, lots of special details like a two story bird house (chinese chippendale no less) with parrots top to bottom, stained glass, etc making you feel like you walked into a land version of the titanic. Polynesian was nice but just did not IMHO capture the spirit of hawaii as much as GF did its spirit of high victorian. Again though, look down, as many if not more will say the opposite, so again I ask, which fantasy (disney style) most closely fits your and your family's fantasy and comfort?
