My opinion....it's tempting to enter a lot of trials, but it can get expensive real quick, especially if it's YOUR first time and your dog isn't quite ready.
I went to these trials once....the time I went, the shows were HUGE, and noisy. Had to park far away and had to pay for that too. There was even a flyball tournament going on in one of the rooms! Obedience was in its own room, so a bit less distraction there.
These shows close this Wednesday, so if you ARE entering them you should probably enter online.
