Purchasing tickets, holiday to USA!

So, now it's been a while, and I'm in a rush. How cool, huh? My husband and I are leaving for US with the children and Coleen, and we still don't know whether to purchase Georgia Tech Yellow Jackets tickets, Maryland Terrapins tickets, or Miami Hurricanes tickets or... North Carolina Tar Heels tickets. Yeah, right, we're going to have fun. ^^ I'm sure Coleen is gonna be excited by the events, and this is going to be his first holiday abroad. Dear little robot! :) Hopefully we get to travel to Japan one of these years too. Let's start saving!
