Sounds great. You'll want to go to North Gate prior to the game. The tailgating scene for basketball is pretty weak.
If I were in your shoes, I'd come in early enough to tour the campus a bit if you've never been. Plenty to see there including Kyle Field, The 12th man statue, The MSC, (take your hat off when yall go in), maybe even see the corps doing drills on Simpson Drill field, and we obviously have the Bush Library here which is basically on campus too if yall are in to that.
Eating/Drinking is whatever you'd like it to be. Further off campus, we've got great Wings places like the one owned by Former Aggie and NFL player, Mark Dennard. His place is Wings N More on University Drive. If you want a little more upscale dining, you'll have to venture off the well beaten path a bit more, although The Republic Steak House is also on University. Bring your wallet.
North Gate is your bar center basically, but there are some pretty good eats down there too. Depending on what kinda of mood you're in, the bar scene is pretty wide open. Traditional "Aggie" spots would be the Chicken, Fitzwilleys, Dry Bean Saloon, Dudley's, The Corner Bar...... those are the only places I go because I know the owners pretty well through business. That and we end up there most Friday afternoons.
You can park at NG in the parking lot behind it, or in the garage, but you gotta pay. It's cheap though.
As for Reed Arena, you wont have trouble parking at the gym actually. You may just have to walk a bit, but you cant get lost, its big and stands alone. While you're near, you should try to check out our newly renovated baseball field. Its right across the street from Reed. Cant miss it.
You'll have fun for sure, just let me know if you have questions on anything. I'd be happy to give you directions or any links.
What are yall interested in?
