Ok I'm most worried about this part of our vacation. We have reservations to use Disney Transport to the Pop century. We are flying from Japan to Atlanta then Atlanta to Orlando. Our plane arrives at night about 7 pm 1) Is using this transportation as difficult as I imagine? 2)I'm flying Delta--does that help or hurt the process? 3)I relly don't want to wait a long time for my bags at the hotel after almost 24 hours of travel I want to go to bed. Is it easy to get my bags and then recheck them?
