Only worth it if you use the group-on deal.
The Kajama is just a commercial ship that takes you out into the bay for an hour and then spins around to come home.
The crew is composed of college students and they do a good job of maintaining the ship.
The food is a little pricey but nothing that you wouldn't expect from Toronto.
Overall, the ship is clean, the crew is friendly, and it's a nice spot to take pictures.
