I don't know enough about the other ones, but I've taken 3 teams to Dreams Park and years later the kids still talk about it as the best time of their lives in baseball.
There were 60 to 80 teams in it every week at the time, ranging from town "all star" teams to heavy duty elite travel teams. I've taken both types. The schedules are mixed, you get to play some town teams, some travel teams. The town kids won a few, got smoked a few times, but they didn't seem to mind losing too much, they were having a great time regardless. Another town team near here went to one of the other tournaments in Cooperstown, not sure which, but there were only something like 15 teams in it and they didn't have the same experience, it was fun I guess, but they wished they went to Dreams Park.
