It's probably between a three and a four, but if you approach the ride with a positive attitude, you're likely to have fun. Bonus points for charging reasonable prices for drinks to their trapped audience. If you ride the Goodtime, chances are it's for their Friday booze cruise or one of their two hour lake/river tours. It's all pretty no-frills (in a good way) and it's a cheap way to get out on the water and see the city from a different angle. The tours are narrated by a recording that covers some basics. It's not a bad way to while away a couple of hours.
