Does the E21 bus allow passengers with baggage? I read somewhere that this bus caters to mainly airport employees. We are a group of 4 with one bag each. The bus is convenient for us because it stops near our hotel, the Dorsett Kowloon Hotel on Anchor St. Or can we just ride on the S1 bus to Tung Chung MTR, then stop at Olympic station? Which is the shorter ride?
