We paid the extra for the preferred location, requested Martinique, and loved our room there. It was worth it to me to be close enough that my sons could walk to the food court and pick stuff up if they wanted, but any of the locations mentioned already by other posters would be great.
I had no trouble getting my requested location, calling a few days ahead to make sure it was still listed on my ressie, then when we checked in we got our Martinique room no problem.
Make sure you check out Safetymom's photos, and also the FAQ threads... she has a lot of great info posted on there, and it was a big help to us.
