Our posts hit at the exact same time, so I didn't read your second post in time. If AKL appeals to you, then WL's plans were drawn up by the same architect and sort of has the same idea as far as the lobby goes. The themes are totally different though, of course. At WL, you can boat over to MK, which would be good with your kids because you can roll your stroller right on and off the bus. If you have a sleeping child, leave him/her right in the stroller and just roll it on the boat.
As my post above stated, the easiest way to get back and forth from MK is to stay at a monorail resort -- Poly, CR, GF. At CR, you can walk back and forth to MK, besides the monorail. Many people don't like the theming of CR -- they think it is sort of "blah," but I think it's exciting to be right next door to MK (in my opinion). Poly is laid-back and has a hawaiin theme. Separate long houses, though, and a main building if that matters to you. We've never stayed at GF but have eaten there. It's very classy and pretty, but I have no idea what it would be like to spend a trip there.
With monorails, you can also leave your stroller out and kids in it and just roll it right on the monorail. So stay late at the parks and let the kids fall asleep in the strollers and then just monorail back to your resort. Very easy! You may even find the kids will be so tired that they'll nap right in the stroller during the day. Then just find a quiet restaurant and enjoy a snack while the kids sleep. Not sure how your 5 year old will do as far as sleeping, etc. My twins are 4 and they still slept in the jogger whenever they got tired. I think they will still be the same at age 5.
