Just back from a stay at the Poly. Yesterday morning, there was no monorail service on either line. I was at the TTC at 7:30am and did not make it to MK in time for 8am rope drop. An hour and half later at 9am, there was still no monorail service from either the Poly or TTC. So be sure you leave early enough to allow for in case you need to take a bus.
