My DH has done this, and thoroughly enjoyed himself. It gets asked about every so often on the board, and I've never heard anyone say they didn't have fun.
DH did say that he'd hesitate taking a younger child, because it's a lot of money, and if they aren't really into fishing, they might be bored. DS is a big fishing fan (he's 10 1/2), and he'll probably go next time (if we can talk him out of the club, which he also really likes on the island).
