I agree.
We'd heard for several years what a great shortcut it was to walk to the TTC. Too true!
After a one-nighter at Poly, we're believers. It's not only a very short walk but beautifully landscaped.
We stayed in PagoPago which is right at where the entry to the pathway is.
If in another building not near PagoPago, just walk through the GCH to its main entrance, take a hard left onto the sidewalk which will take you directly to the pathway entry.
