My first trip to C-link was the NFCCG last year, I had a great time.
Obviously the after game party was EVERY WHERE in the streets, you couldn't miss it.
If you want to hang with the members from .Net, Temple Billiards is the unofficial/ official meeting place. Easy to find, just google map it. 5 min walk to stadium.
They have incredible BloodyMarys , good food, great selection of brew. Blue Thunder guys usually stop by for a song or two.
For me it was AWESOME.
I don't see a reason to look any further for a good time pre/post game.
Unless you will have children with you, if so, some of the others will need to share their thoughts on a good time w/kids.
I know that the family experience can be had as well, I just can't speak to that side.
Edit: although I haven't bought tickets yet, wife and I are planning a trip in from Houston for the opener as well.
