I think our lovely brunch queen, Bunny, who happens to be a local, would have some good options for us!
Columbia is a super suburban town, not much choice of places with booze in the morning. I researched Brunch places the last couple of years (not this year, I'm lazy - anyone looked recently?) and the best is Eggspectation. It's about 5-6 miles from the venue. And has a full bar and decent food.
Eggspectation 6010 University Boulevard Ellicott City, MD 21043
Gates open at 11:00, meet at 10:00? Earlier? Later?
I can say from experience that the later you go the more horrific traffic will be. The schedule will come out next week sometime, might help folks decide how early they want to get there.
That place was super amazing. Great drinks, delicious food, and they don't even get mad if you make a drunken mistake and walk into the men's bathroom.
