We were in the same boat you were!!! We LOVED the WL and thought we'd never find something better. Well we just got back from the AKL and it's now our favorite-lol.
We even went back to the WL to compare the 2. Here's my thoughts........................
The Pool-The pool is much bigger at the AKL. The AKL has 2 hot tubs(as does the WL) but one of them is larger, about twice the size. Then there is another hidden hot tub about the size of the ones at WL. They both have a water slide that's about the same.
The *food court*. The AKL, Mara, is run differently then the Roaring Forks at the WL. At the Mara, it's much larger and you order your food and then they bring it out to your table, either inside or out. They have a bigger menu then I remeber the RF having, I think. They have a lot of desserts and bakery products as well, great chocolate chip cookies-lol. In the sitting area there is a TV that plays Disney movies too. We ate at the mara alot and really enjoyed it. The only thing they didn't have is when we were at the WL my daughter got this cool kids meal that came in a little Roaring Forks lunchbox she still uses for crayons now. They didn't have that at the Mara but then I don't even know if they still have it at the RF-lol.
The rooms- Are very similiar in size and design, there are no major differences.
The view- We had a courtyard at the WL and a savannah at the AKL. Both were great and equal in their own ways.
Then lobby- The WL lobby apears larger then the AKL, not sure if ity actually is or not. Both are beautiful, the AKL had more little paths and decorative bridges in it. They also have a suspended bridge that 's on the 4th floor. Oh the major difference is the lobby is on the 3rd floor at the AKL, it took some getting used to since our room was on the 2nd floor and we went up to the lobby. Different but no big deal-lol. The lobby at the AKL also has a lot of overlook areas onto differernt levels. you can look down onto the bar and Boma restaurant. They both had TV's with videos. They are both beautiful in their own ways.
Transportation- The major difference here is that the AKL is all busses. I worried about this but was proven there was no need to. The busses were great, in 2 weeks the longest we waited was 15 minutes and that was only 2 times. The rest of the times it was FAST. I've seen people complain about the long rides but even to the MK it only tyook 12 minutes or so. They were rarely crowded even the week after Easter and we didn't share any busses with other resorts.
Overall I fell in love with the AKL, I thought it was just wonderful and I didn't want to leave. We even went back to the WL to visit and compare-lol. Even though I loved the WL and thought it coould NEVER ever be replaced as my #1, the AKL did it, I was very surprised.
I worried so much before we went and I shouldn't have the AKL was NOT a disappointment.
I hope you have great time, I'm jealous I want to go back-lol. If you have any other questions please just ask! I hope this helped!
