1. I really think the boat ride from the Poly to MK is excellent. You then just walk over to the bus area to catch the POR or POFQ bus to hotel.
2. For a longer, far more excruciating venture, take the DTD bus to DTD, and then appropriate bus back to hotel. Guaranteed 1 to 1 1/2 hour trip!
3. You can also monorail back to MK, and take your bus back to hotel from the MK area. If you do this, remember to ask to sit in the front of monorail. (Not a given but fun to do).
PS. Our family used to have transportation relays around the World. Alternate routes with "who will arrive first?" Since the demise of the TTC as a hub, it's not so interesting!
