OK, here goes: (in no particular order)
First one goes express from TTC to the MK and back.
Next one goes from TTC to Contemporary, to Grand Floridian and to Poly and also stops at MK.
Last one goes from TTC to Epcot and back again.
As far as I know, you can ask to ride up front in any of them. It is at the discretion of the CM driving the monorail. They will take up to 4 adults up front.
Hope this helps!
