You know, I think you are right about DTDs opening time, that would make sense because I remember the boats at POFQ didn't start running to DTD until 10:00. Definitely wouldn't be worth it to head over there for just an hour!
DTD opens at 9:30. Buses run earlier than that due to the BBB appts. at WoD. Again, I have no idea about the times for the balloon though. Hope that helps a little!
