All the mods are great. I stayed at PORS last Nov and loved it and just came back from a stay at CSR and it became my new favorite moderate and I didn't think I would enjoy my stay there but I really did love it. I will note this info though, PORS was extremely quiet the majority of the time. CSR was not (then again this resort was 95% full but still felt empty at times but there was more noise) as it had plenty of people because it was Supersoap weekend, last weekend for Food & Wine Festival, the conventioners, etc. However, you could've easily have had a quiet pool to yourself, walkways to yourself and even though the main pool had a lot of people, plenty of chairs were still available. I do love this resort and wouldn't hesitate to stay here again.
GL in whichever one you pick and have a great time planning.
