I think we actually spent more like 20 min on the bus. The bus seemed to go around the long way (we drove past OKW and SSR if I remember correctly) and the the first stop was at Marketplace, but we wanted to get to PI. Unfortunately our bus did not continue there, so we hopped on the next bus and it took us another 5 min to get to the PI bus stop. On the way back, the trip was more like 10-15 min.
