I will chime in here as well, just to provide that little extra reassurance and some creative ideas. We stayed at AKL for 10 nights back in January with our 10 month old and two year old. It was absolutely fantastic, and we had no complaints. Here is what I remember...
1 - The bus service was exceptional. In nine days of going to the parks, there was one time that we had to wait more than 5 minutes for a bus. We were very pleased.
2 - We booked two "free" days into our trip, just to enjoy the resort and give our little one a break. Being close to Animal Kingdom was awesome. On both of our off days, I took our two year old over to AK for the last 2-3 hours the park was open. It is amazing how much we could get done in just a couple of hours, and then be back in our room within 10 minutes of park closing. The last day we were there we rode Kilimanjaro Safari three times in a row, just before the park closed.
3 - The food was awesome. We walked from Jambo House to Kidani Village for lunch one day and it was my favorite meal of the trip. Sanaa was delicious! We booked our reservation at 11:00AM right when the restaurant opened so that we could sit right at the windows.
4 - If you are staying in a Standard Room, do not be afraid to ask for "People Pen" or "Partial Savannah" view. We did and were pleasantly surprised with a view overlooking the Savannah. We had all kinds of animals right below our balcony and did not have to pay the extra to get the view.
5 - There are lots of activities for your kids at the resort all throughout the day. There are also beads that you can collect when you complete activities. This was a nice, "free" memento that my son could take home to remember the resort and the things he did there.
Enjoy your time! You will not regret it.
