I've stayed at all 3. They are all really nice. If we have the extra money, I'd choose AKL. The theming, food & rooms were really great.
POR was very nice; the theming was wonderful, the food court ok. No problems.
Then I stayed at CSR and loved it. I really like the theming, experienced friendly CMs, had a clean room - and really enjoyed the pool & hot tub. Plus I LOVED the Pepper Market. Well worth the 10% service charge. Not confusing to me, and a great variety of tasty food.
IMO just because other guests experience bad service/CMs at resorts doesn't mean you will.
Personally, I try to pick our resorts based on the theming that appeals to me, as well as the resort features/amenities. I will not steer someone from a resort or restaurant based on my experiences; I can share mine, but it's truly up to each guest to form their own opinions. Saying one resort is better than another is subjective.
