Hello!
I hope this helps! I have a four-year-old, too, and we hope to make the trip together in the very near future (maybe this fall). The last time we stayed at the Wilderness Lodge with my sister, and my little girl was only two. It was August 2006! DH can never seem to find the time to go with us, so we have to go by ourselves, and it seems to make our room selection even more important.
First check out this map of the Lodge:

I would definitely ask for a room in the Bear's Face. Those rooms are so amazing. Some people may complain about the noise from the lobby, but we couldn't hear it at all when our door was closed. We were in our room for naps during the day and to sleep early in the evening. We never heard a peep. And to me, to open your door and see the BREATHTAKINGLY BEAUTIFUL lobby below is beyond words. It was so special. It was every bit as special as seeing the courtyard, pool, and Bay Lake from our balcony. And that was pretty fantastic, too! We could even watch the Electrical Light Parade on the lake every evening from our balcony.
Every time I walked down one of the long corridors, I was so glad that I had requested a room right above the lobby! Our room was 5079. We were right next to the elevators, although all of these bear-face rooms are very close to the elevator.
Here's a list of the other great rooms:
5067, 5069, 5071, 5073, 5075, 5077, 5079 and
4067, 4069, 4071, 4073, 4075, 4077, 4079
We checked in early to get it (around 8 a.m.), and the lady said if we wanted one of those rooms that we couldn't get into it until after 4 p.m. That was okay with us. They stored our suitcases for us, and we went out to eat and explored Disney World. When we checked back at 3 p.m. (just in case!) our room was ready. And it was well worth the wait!!! The cast member who delivered our suitcases made mention several times of how nice our view was--and he was right.
I hope you are able to get a bear-face room. If not, my next choice would have been to have one of these rooms:
5035, 5037, 5039, 5041 and
4035, 4037, 4039, 4041
OR
5123, 5125, 5127, 5129 and
4123, 4125, 4127, 4129
These rooms do not look out over the lobby (inside the Lodge), but they do have balconies which offer a full frontal view of Bay Lake. Views of Bay Lake are among my favorite in all the World.
Any room will be nice, though. I would ask for floor 5 or 4. I enjoyed being close to an elevator, but it isn't a necessity. I just prefer not to walk down a long corridor past a lot of rooms when I have a toddler who likes to squeal.
Let us know what you decide and how you like it! If I can answer any other questions about the Lodge, please ask!
