Concur with all prior posts. Get a cab, cheap and easy. Few months back, taxi ride from Suzhou train station to the then Sheraton Suzhou was less than 30 RMB. Use the cab to go from sight to sight also. The so called Tourist Buses (1 or 2 RMB) are extremely crowded, but cheap! Many Chinese tourists use them.

I also lament the loss of Sheraton Suzhou.
