Ok, so checking in online and printing your boarding passes at home 24 hours before the outgoing flight is straightforward, but how does everyone do the return flight check-in?
Last year I was able to check in using a computer at Guest Relations at Epot. You should be able to do it at any park. Or the front desk at your hotel would be able to do it as well.
Three weeks ago I went to guest services at Magic Kingdom to get my SW boarding pass, they were very helpful and we were the only people out of a group of 15 that got A boarding passes.
I was there with a party of 9 from Aug3-8 and on the 7th at 8:00pm went to guest services at Resort (POR) and he was more then helpful.....we all got A's....
You can also have someone at home check in for you and confirm your A, B or C. Then when you get to the airport you just have to reprint your boarding pass.
