I think that in some cases you might get in based on the waiting list.

As for venue size, in most cases I don't think thats a great reason. For instance the GLR this year has been capped at 59 - last year there were 66 teams. Also, at the CR we are currently capped at 48, but our venue is as big as the GLR one, but we have ten fewer teams (altho some spots are set aside for local teams that are still being recruited).

I bet MOST regionals that are "full" right now will probably see another 5 teams added to their lists b4 everything is said and done.
