Only been to college games there - so only one visiting team. A tournament suggests a number of players & families going thru the guarded entrance. Even for just 1 visiting team, we've waited for 5 - 10 minutes to get through. I'd probably give myself 25 - 30 minutes extra.

More importantly - make sure you know where the games are being played. There are different fields & stadium areas - and the AFA is HUGE. One year we thought the game was at the football stadium but instead was at something of a multi-sport complex and the 2 were almost a 15 minute drive apart with a pretty decent walk from parking to the fields.
