I'm not sure if you got the answer to your question or not, but we also got our boarding passes early. We didn't want to have to hassle with it at the airport. We stayed at the All Star Movies. The easiest way for us to do it was to go to Animal Kingdom and then take a bus to Coronado Springs. We were also told that we could go to the Contemporary, but you need to go during business hours. I think you have to at Coronado Springs too. Anyway, it was a hassle until we figured out that we just needed to go to CS. I would go to the closest park to your hotel (or downtown disney) and then catch the bus to CS.
