assuming your 7 year old likes hamburgers like most 7 year olds, burger bach is right there in the new harris teeter plaza
on campus, the loop in the BC would be pretty kid friendly as well
definitely chekc out the new "improved" west union
go downstairs before the game and walk onto one of the corners of the floor. They'll stop you and not let you go too far, but at least you can stand on one small corner of the floor
The team goes in and out of the tunnel several times before the game
~40 minute -> to the locker room
~30 minute -> out for layup line
~12 minutes -> to the locker room
~ 6:30 -> out for game
If you happen to be down there, you can see the team run by. The usher at that door is pretty good with kids...but he'll probably have his hands full with students for this one, and they may not even let non students through that door. try one of the others if you just want to get close to the floor
It's much harder to get on the floor after the game these days since they clear everyone out pretty quick. But if you get down quickly, you may be able to get into section 17 as the students are heading out, suggest the south side...and you ought definitely be able to walk between press row and the ropes and actually be on the floor.
There's memorabilia in both the south lobby where you enter and the museum.
Get there on the earlier side before they/we run out of programs.
Walk around the seating bowl and take pictures of the banners (or the worst seats in the house, as some of us do...)
