As far as fastest to MK.. I first tried walking to BW to take the bus, but that backfired as there were a lot of people waiting for a bus there... probably 2-3 buses worth. And this was at 8am. So I called an Uber, which I should have just done from Dolphin.
2nd time I just walked down to Dolphin bus. If a bus was there - took that. If not, called an uber. Both drop off at TTC, then took express monorail to MK. Seems those come around often enough.
