I think that's what I'm going to do. I'll time so that I leave the front entrance no later than 1:30. That means start leaving around 1pm if I'm at the opposite end of World Showcase.Personally, I would just drive when park hopping instead of relying on disney transporation, unless you just want to ride the skyliner or monorail. You will get to your other park quicker unless you get lucky and don't have to wait at all on the bus, etc.
