Haven't been to any except Diamond Nation but I would NOT make that one the best - not by a long shot. Reasons why:
- Very short time limited games so they can pack huge numbers of games into the schedule & make most money possible
- Entrance fee to watch your kid play so they can make as much profit as possible
- No coolers allowed in, so you have to buy their concessions and they can make as much profit possible
- Fields extremely close together so constant incoming foul balls to watch for
- They set it up so their house teams play the weakest teams in pool play and best teams play each other
- Not an easy area to get to, and games are often spread widely (early & late) across 2 or 3 days so they can get the most money from each weekend with a huge amount of teams.
- Temporary metal "fences" for the younger divisions because they play on divided 90' fields
- Central/North Jersey traffic
In short, it's all about the money at DN.
So maybe I am a bit of a softie for Diamond Nation but....we spent 5 to 7 weekends / mid weeks every season there for the last 6 years, I love the place.
Yes the Diamond Jacks Supers get a walk through pool play most of the time, not always but plenty of times. Yes the field are a little close but they have netting for the fans...yes they charge a gate fee but they have invested a shit pile of money in the location.
No it is not hard to get to, it is actually easy to get to which is why it is loaded every event at every age group months in advance, the completion with a few exceptions is very good, if you want to play good baseball in the Mid-Atlantic / NE at age 13 and higher this is your place, you want hard to get to? reference Baseball Heaven.
They use temp fences for the girls, they don't run young kids on the big fields. Ripken is still the king for 12 and down.
They bring in teams from Florida to Maine and also from the mid-west, they bring schools like no other events in the area. For the big tournys it is not uncommon to have 100 plus colleges on the sign in list...
