We stayed in the Poly/concierge last fall. I really doubt we'll ever stay anywhere else, at least not with our kids. We all loved it. We had stayed there before several years ago but it seemed that the concierge service was so much better this past fall. We did stay at the CR several years ago, not concierge, and it was nice but just doesn't compare to the Poly! For our family, once we figured the difference between concierge room vs. non-concierge room, we more than made up the cost difference with the food and drinks available at the concierge lounge (breakfast there every day, snacks, drinks anytime and several nights the appetizers were so filling that they were more like meals - one night they had steak or chicken on skewers, noodles and spring rolls - I've read they don't have the spring rolls anymore, they'll be missed.) We have three growing boys so you know they eat plenty!!!! Also, you'll love the extra service. If you've never had concierge services before you need to try it. We just love the treatment. When we were there in October the staff all bent over backwards to help us. One in particular, Marc, not only helped us with some planning and priority seating reservations - which of course is his job - but he also took the time to really get to know us and to know our boys. He knew each of the boys by name and made it a point to speak to them and give them extra attention. I just can't say enough good about the Poly! Although we didn't think we'd be going back for a few years we're already planning another trip for next fall! Can't wait! Good luck with your decision-making!!!!!
