We recently returned from a trip at the AKL, and we had a room overlooking the construction. I totally thought it was going to be a downer - but I never heard it. We even slept with our slider door open on most nights/afternoons. We returned to the room every day for about 2 hours so my 16 month old could nap (and us, too).
My biggest complaint about the AKL was the fact that you had to walk through the smoking section to get to the buses.
We ended up cutting through the gift shop every time just to avoid it.
Little "petty" complaints - there are no screens in the sliding doors to the balcony, and there was no room to set up the pack-n-play. We have no issues with co-sleeping, so it worked out for us.
Otherwise we had a great trip - I was afraid the construction would keep the animals away, but all 3 giraffes and other animals were there every day. My DS loved it and had a blast! We will definitely stay there again - but I hope they can do something about the cost of internet.
