Ahh, yes, I remember thinking that it was roughly the same time. Still much better without the traffic, but significantly more expensive if one has access to a vehicle already. I found myself thinking I would like to take it more, but it wasn't that fast, plus with having to get to the train station ahead of time and then get transportation when I arrived, it was actually more time consuming.
It was very scenic though and I very much enjoyed being able to walk around and also walk to the food car to get a beverage and sit at one of the tables there.
