My son went twice; 10u and 12u.
They put on a good show but they do it the DreamsPark way. The kids get caught up in the games, trading pins, buying bats and being kids. You will see teams that vary in talent from local rec teams to top flight national powerhouses. The fields are all about 200' to the fence but the fences are high surrounding the entire field and if I recall, when you are in the field, there is no breeze and it is very hot. Take an umbrella for shade as there is no shade for spectators. Having said that, perhaps things have changed over the years, but I'd rather you be prepared. The trip to the HOF is good and the activities for the kids make it a fun week. My son can still remember some of the teams they faced and he got a great picture of what top players/teams look like. I hope you enjoy and I'm sure you'll hear some good tips from others.
