Wow, this is clearly a POR leaning thread, so I hope that I don't offend anyone......
I have stayed at both AKL and POR-Alligator Bayou within the last three years. I have one son who was 6 and 7 at the times we stayed in both. My husband and I are very outdoorsy and don't mind walking at all. I bore you with these details because I think it is very important to consider your sources and how they compare to you when assessing information. All that said, we are going back to the AKL and probably never staying anywhere else again. We have tried lots of on property resorts from value to deluxe and this one won for us hands down. We didn't stay in a Savannah view, but felt that our opportunities to interact/view with the animals were plentiful. The atmosphere is warm and comfortable. The walking at either resort obviously depends on room location, but POR is soooo spread out and we felt like we had to hike for everything from busses to mug refills to the parking lot and we hated it. Much more convenient at AKL. We found the food court to be adequate, and the food options just fine. It was smaller, but also less crowded than POR as it serves far less people. However, we don't tend to eat in food courts much for anything other than snacks and breakfast. The staff was AMAZING. We got lots of personal attention, especially my son. While I've not had bad experiences at other resorts, at AKL we felt they went out of their way for us. The activities for my son were so numerous and fun that there were days he asked to not go to the parks and just be able to stay at AKL and do activities there. The pool is very nice and didn't seem very crowded. POR main pool is great, but always seemed very crowded. The courtyard pools, however, never had a soul, but my son found them boring. POR does have a great boat ride to DTD, also.
It all depends on you and your family, but I can't tell you how much we enjoyed AKL. We felt that we had a little "down time" from the park chaos, but without losing any magic. At POR, we felt the chaos followed us everywhere - busses, food court, pools. So there's a little more input. Hope it helps!
