Of course you would think a deluxe is going to be 'nicer' than a moderate, the question is, do you care about those things that make it nicer? We hardly ever use room service, maybe for a pot of coffee in the morning. The room size difference between a deluxe and a moderate isn't enough to worry about, especially for just 2 people. Inside corridors? I found you hear more noise at night from kids, and adults, using interior corridors than outside corridors. I've stayed at the Poly twice, and I've stayed at CSR & CBR. To tell you the truth, if I were offered CSR and Poly at the same price, chances are I would choose CSR. The ONLY thing Poly might have over CSR would be the monorail. I think a lot of people that use the deluxes spend more time hanging around the resort. We visited Poly on our last stay at CSR and it was a nigtmare, the pool area looked like some kind of third world food giveaway...people EVERYWHERE, kids running, people screaming. We saw folks coming down to the pool and just turning around and leaving because there was nowhere to sit and no room to swim. This was during a slow season. The food choices at Poly are good if you like 'Ohana or Kona Cafe..The counter service place there is the pits, small selection, paper plates, and the place was an absolute mess the day I looked in. Trash everywhere, food on the floor.....lol, my kids wanted a snack and I wouldn't let them get anything to eat at that joint. So, for a long round-about way of answering your question, no, I don't find it that much nicer.
