I see this was posted a while ago, but I had a stay at the cabins so thought I would comment with my thoughts. Your mind is probably alreayd made up on a resort, but I know there are lots of larger parties who consider a cabin vs. a more standard resort.
We got a really great deal on the cabin thanks to a promo disney was running at the time of our booking. I was nervous about not being in a hotel and having amenities right there since, like you, Ive stayed at deluxe resorts the past few trips. However, my group (5 adults) absolutely loved it.
PROS:
-Its actually a great amount of space to spread out. With a the full kitchen it feels almost like a one bedroom at a deluxe resort but cheaper. And it looks beautiful! The couch was a little worn already, but the new renovations to the cabins make them feel wonderful.
-Speaking of the kitchen, we ordered a bunch of groceries and saved lots of money on meals. Most breakfasts were at the cabin, plus a big cookout night with burgers (thanks to the outdoor grill!)
-Its super private feeling and very unique. It's quite relaxing to escape into the sea of green trees and nature, esp after a crazy park day.
-Location. I love having a direct transportation access to MK. And the resort boats get you to Contemporary and WL to expand your dining options. It was easy to take time and go to Geyser Point and California Grill.
-Golf Cart. Honestly, I wouldn't stay here again without it. It was such a fun addition to the trip driving around the grounds and we didn't have to wait for internal buses. Some of our best memories from the trip were driving the cart around.
-Activities. You can spend a lot of time at the fort having fun. We always plan non-park days to relax and it was a perfect resort for that. Those days were filled with horseback riding, swimming, electric water pageant, Hoop Dee Doo, campfire sing-a-long. The Davey Crockett bar and Trails End are affordable eating options.
CONS:
-Managing the bathroom can be a bit of a hassle. I chose a cabin across the street from the comfort station/pool so some of my party could shower there, not realizing that the comfort station in the cabin area does NOT have showers. Luckily we had some very early risers so shower times were able to be spaced out, but it does require some planning in the morning to get everyone showered and ready with only one bathroom (and for reasons unknown, only a single vanity). At least I was just a quick 30 second walk to the pool!
-The resort is very large, so you do need to plan a bit more travel time than normal for places outside the MK loop.
-Unlike deluxe resorts, you cant just take an elevator downstairs to a bar, coffee stand, store, etc. So that is definitely a shift in how you vacation. We stocked up on coffee, wine, snacks since we had the kitchen, so it ended up not being a huge issue if you do that.
I personally find AoA to have a more loud and rambunctious vibe to it, so if a good price can be found for the cabins I would prefer the peaceful atmosphere of fort wilderness. The biggest change I think is that certain amenities are not right at your fingertips. However, a cabin gives you alternate ways of experiencing them (a full kitchen for meals/drinks, or using a golf cart as a fun way to get to the store). Just my 2 cents!
