Cash only lines move way faster than the other ticket lines, but the wait wasn't too bad even though we were there at 2pm on a weekday. The ferries include fare back. During the summer they leave every half hour if you're going during the afternoon.
Quite a few people bring their bikes on - they even fit a minivan on the way back.
Clean, quick and efficient - they don't really try to squeeze too many people on at once, which makes for a more comfortable ride. Also, if you're 19 and under you get reduced fare!
Also you get an awesome view of the skyline on the way there!
