We used the Harbor Club at BWV our first trip in 1997 when our son was 4. He thoroughly enjoyed it and it gave us time to hit a nice restaurant and rides like Space Mountain that he couldn't go on. We stayed at WL in 2000 and he loved the Cub's Den so much he kept asking to go there. It was pricey (what at WDW isn't), but worth it for the enjoyment he got out of it. They had video games, regular games, movies, snacks, other kids to play with ... And we got some adult time. Win-win!
