If you have to care about the price, NO! I love the Poly, it is beautiful, strong theming, perhaps the best in all Disney resorts and the location is stunning.
But the Poly has it's flaws. When I stayed there last September for 5 nights a childhood dream came true as I had dreamed of staying since I saw it the first time in the early 80ies.
And as I said the paradise has some flaws. If I pay such an extraordinary amount of money I expect first-class hotel service, first-class housekeeping, first-class rooms etc. I mean honestly you pay as much money (or even more) for the room as you pay at the Waldorf Astoria in NYC, the Adlon in Berlin, the Ritz in London, The Breakers at Boca Raton etc. In these hotels the management would consider it a major flaw if you would find any tiny stain in your room.
But the rooms and especially the housekeeping in the Poly are sub-par, cleanliness definitely is a problem. The housekeeping didn't manage to wipe our (really) dirty windows clean in FIVE days and after three complaints! Cobwebs on the balcony were not removed either before I had complained twice at the reception. The bathrooms are nice but definitely not deluxe standard, the furniture is the same, it looks used.
It's a beautiful resort but I would never pay the price again as long as they don't improve service and housekeeping. We prefer WL instead although the rooms there are actually to small for a deluxe.
Disney resorts were always overpriced but it's getting ridiculous by now.
