Getting to Pearson

[Pheidippides]

I have a meeting near Pearson (the Westin) coming up.

Google is telling me to take the Kitchener GO train and transfer to the TTC 52.

Google's other suggestion is the #25 GO bus to the MiWay #107.

Does anyone have any experience or preference with either of those options? The time difference according to Google is 6min, but the unpredictability of the bus on the 401 troubles me.

Are there any other options I should consider?
Thank-you!



Also, when I look at the TTC 52 route information it says that, "PRESTO cards can only be used on TTC buses in Toronto."

The Presto page has a similar blurb:
"Currently, when using TTC buses that operate in Mississauga you can only pay the TTC portion of your fare with PRESTO. When you board a TTC bus in Toronto you can use your PRESTO card to pay your TTC fare. If your journey ends in Mississauga, you must pay the additional fare with cash or a MiWay fare product. When you get on a TTC bus in Mississauga you must pay your MiWay fare with cash or a MiWay fare product. If your journey ends in Toronto, you can then tap your PRESTO card to pay your TTC fare."

If PRESTO can be used on MiWay, on TTC in Toronto, why not on TTC in Mississauga? Something to do with lack fare recovery/integration between the TTC and MiWay?
