I have to second the vote for Tokelau. We have always stayed here except for once when we were upgraded to a MK view in Tahiti. We like Tokelau for the central location. The proximity to the laundry facilities is nice for when we want to wash up a few things before heading home, the parking lot is a straight shot from the end of the building, it is close to Sunset Point and it is equidistant between the GCH and the TTC for monorail transport to the MK and Epcot respectively. We don't use the buses, but the stops are right at the walkway from Tokelau when going to the parking lot.
I hope you have a great time. You will enjoy yourself wherever you go.
P.S. I know this is debated all the time and there are people that say it no longer works, but I always send a poem to the front desk 10-14 days in advanced which I instruct them to read to the music of the Mickey Mouse Club theme. In it, I make my request for Tokelau and a specific room and tell them a little bit about what makes this trip a special one for all of us (once was our 50th visit, once we were with three people in their late 20's who had never been etc.) The last time we had two birthdays and when we checked in, the front desk person greeted me and when I told her who I was, she did her stuff and said, "OH YES! You are the one who wrote the poem!" She then went to get one of the other ladies who remembered me from before and even remembered some of the lyrics I had written in past visits. So, I know what others say, but I can only say that from my experience, it has worked as recently as October, 2009.
