and really liked it. My son and I sat on the last row facing opposite the rest of the folks, and we got to take some excellent pictures without any thing blocking a good shot.
it took about an hour or so, and then it ends up at the Depot, which is at the end of Duval Street. Very easy to walk to shopping and a couple famous bars such as Sloppy Joe's and Hog's Breath. It wasn't too long of a walk back to the ship.
You got to see all the famous highlights, and I would say it was well worth the money.
On Carnival, the Conch Train was pulled up next to the dock, so you didn't have to walk over to town to catch it. Not sure how Disney is doing this, but bet it is the same way.
