Great Wolf Lodge is great, we had a good time there first week of December. Similar price ($130 per night). Just be aware there are taxes and resort fees, so the final price is much higher. I definitely recommend a visit if you have kids who enjoy water parks.
I know there is a shuttle to DLR advertised and it is not free, but don't know more specifics than that. We just drove to M&F garage since we have AP with free parking, but there could be better ways to do it. I've actually never been to the Toy Story lot.
Edit: I couldn't find anything about the shuttle on the official website, but according to this website the shuttle is free:

Not sure how accurate this info is though.
