Oh, I thought this was referring to Disneyland CA. How does Disneyland CA work then?
DL races also had an early start time. But from my memory it was not quite as early as WDW. I think it was 5:30 instead of 5:00, and you arent expected to get to your corals as early at DL.
Also there are so many hotels within walking distance you don't have to deal with the traffic if you don't want to.
