Exact change only, if you don't have the right amount of money prepair to leave a juicy tip.
It was a nice but short ride, truthfully I was expecting more.
You cannot see that well through the windows and due how they pack it the view is nice but not pictureworthy.
It is really old school, running since the early 1900's, worth a trip for sure.
It gets full, expect to wiat in line but due to two trains running at all times, early morning till past midnight and the ride only going 5 minutes you will not wait long.
The best views are from the upper platform, if you want to save your money just go up there and take some pictures, I think it is about $3 per person one way.
