10:20? You're golden!!! That's really easy to do. Head to the MK and then take either the monorail or boat over. There are two ways by boat...you can take the smaller boat that goes to the GF first and then to the Polynesian and then back to MK, or you can take the big ferry boat. That takes you to the TTC..you can walk to the Polynesian! I love that walk. Takes under 10 mins.
Or, you can take the monorail.
In any case, be out at the MK bus stop around 9-9:15.
