I'll repeat what I said on another thread. The dorms are a bit rundown, the food is marginal, though edible. There are alternatives to the dorms, like nearby hotels, that might make the players a little happier. The benefit to staying in the dorms is that they are right there -- no transportation issues.
The biggest positive is that there are lots of fields, lots of teams, and someone to put it all together for you. We tried some other venues, but always kept coming back to Cocoa Expo because it was the most inclusive and easiest to deal with.
Also, the parents and other family members stayed on the beach (we always favored Royal Mansions in Cape Canaveral)which made for a GREAT vacation for all involved.
