Considering all the issues Disney has with their computer systems, I'd chock it up to a glitch

. The resort won't even see your reservation for a few more days, so it's very unlikely that you've been assigned something already.
"Close to transportation" is kind of a mute point at the BC anyway, as the boat is located in one area and the bus stop is about as opposite as you can get

. Wherever you're placed, the resort is not really that spread out and you're easily within a few minutes walk of both.
