Airport: DFW or Lovefield, really makes no difference. Both are within 30 minute drive of the areas you want to stay.
Hotel: If you can find one, I would suggest along I-20 near the Parks Mall. You will have lots of entertainment and a very quick 10-15 drive to stadium on game day with no traffic on side street.
Parking: Buy a parking pass from the Cotton Bowl website. Only lot 15 is available right now so, you will walk about a 1/3 of a mile. Yes, it will be a little slow leaving after the game but, it is not bad at all. The worst I've ever seen it was after a Kenny Chesney concert it took 15-20 minutes to exit the lot. (Stub hub has parking passes for lot 12 for $40 which is BELOW face value. Lot 12 would be about a block and a half closer than lot 15.)
Lots will open at noon just like they did for Wiscy. If you want to tailgate, get there early.(I'd suggest lining up at 11:30AM) You have to have a perimeter spot that back up to the grass or contain in your parking spot. They do not allow grills, chairs, table outside the parking lines unless you back up to the grass. For the Wisconsin game we arrived at 11:45AM and they made us wait to enter. Once we entered, most cars were "reserving" 3 or 4 spots. As long as you had a cooler, bag, chair etc to put in the spot, you could hold one. All of the tailgate spots were claimed by 12:30PM.
Day of the game: I'm sure National Alumni will have a tailgate at AT&T Stadium. Other options are the bars surrounding, especially Boomerjacks and Sherlock's. They typically have a shuttle to the stadium. If not, it is a 5-10 minute walk.
Tickets: I have seen some reasonably priced ones on Stubhub, $294 middle level endzone, $400 sidelines middle level, $185 upper endzone and standing room party passes are on sale for $75.
Stuff to do:
Besides the game.... JFK Museum/Dealy in downtown Dallas. Perot Museum of Nature and Science in downtown Dallas has cool interactive exhibits for those with children. Also a cool museum for adults. Dallas World Aquarium is also downtown Dallas.
Bars/Night life:
Uptown area of Dallas if you are into the $30K millionaire seen and be seen crowd.... Deep Ellum if you are interested in getting shot (or seeing some interesting folks), Sundance Square Fort Worth if you just want to chill out, walk around and have a drink or ten.....
Restaurants:
Way too many to mention but, if you are looking for something "special" Lawry's the Prime Rib is where the teams eat each year and it is AWESOME!! Capital Grille is also very good. If anyone has a Q on a specific cuisine, let me know, happy to make a suggestion.
**If you know any Cowboys PSL holders, they can buy tickets this week**
Any other Q's, please ask.
