Four of us took this cruise on a Monday late afternoon. It was pretty busy, but not too bad. The boat is a paddlewheeler, and goes along the New River. Clean and smooth. Bathrooms. Bar service.
Narration is fun, they mainly point out mansions that line the river and canals, telling tid bits and tales of the owners, but not naming them. Some flora and fauna pointed out, too.
You'll stop at a little animal area. They have an alligator show, beautiful birds, turtles, etc. Snack stands, ice cream, basic lunch items. Bathrooms are decent.
Good for first time visitors.
