Although you will get mixed reviews on Disney transportation, I have no complaints.
The bus drivers know where they are going, you don't have to stress over which lane to be in where to turn etc. I presonally find the roads to be quite confusing.
Besides the point is to relax, so sit back, relax, and leave the driving to them!
The momorail is a nice ride, DD had a nice nap while DH and I rode the loop!
Water taxi's/ferries are relaxing.
Oh well, No complaints here!
