We would not classify it as a deluxe, but we do call it the "deluxe moderate" because it has a step up in amenities, has a nicer food court, and has more special touches. I think the food court was to satisfy the business people, but there were things like better transporation, covered seating at the pool, larger hot tub, beach volleyball, better food at pool etc than we had at the other moderates. It is the newest moderate and with anything I believe when they plan they look at previous projects and work to improve some things. We still love POR as well, our first onsite visit and our most frequent hotel to stay at.
We love the "tropical SW" feel of the hotel and each section has it's own style. Beautiful to walk around, especially at night. We went when it first opened and it was great with younger kids and now that they are teens, they love it even more.
As far as the convention folks, they pretty much stayed in the main building area and never were we really aware they were there except when we went up in that area. We pretty much had the pool to ourselves except for the few who did bring their families and some other vacationers. And I really preferred sharing with them than large school groups
As far as the cell phones - they aren't just the business folks. They are in every park and every hotel and every restaurant. Every teenager has one (mine included

), but we do tuck ours away in backpacks and just use if we get split up. My point is they are everywhere.......don't like it, but not gonna change.
