My dh has done the fishing trip many times. He loves it (of course, he loves to fish anywhere!). I think there was only one trip when he did not catch anything. He usually catches a bunch. It is catch and release so it is stocked with some fairly large bass (I think they're bass).
He has gone in several spots...he likes going in the lake behind the contemporary best. It is very expensive, but whether it is worth it I guess is a personal decision. Before we had dd, I think this was the highlight of his trip (he doesn't love the parks as much as I do).
As far as matching you up with other people, I do not believe they do this. You have to make a reservation ahead of time and he always goes at a very early hour, so it's not like there are people hanging around deciding to go. I think you would have to find another group to share the expense with on your own.
