We'll also be staying at the Westin, even though we're based in Atlanta.
As far as breakfast goes, we bring food to our hotel rooms and have the kids eat whatever's there. There is a Starbucks downstairs in the lobby, but if I remember correctly, it doesn't open until after all the robotics teams are gone.
Congrats on Rookie All-Star! If you'd like someone to walk over to the Dome with you, to introduce you to Atlanta and show you around a bit, my team is more than willing. PM me if you're interested. Our teams can hang out at the Westin together
along with the other tons of robotics kids that will be around.
