Unfortunately I arrive the day after the convention and will have to miss the fun. I would like to know though if anyone out there has experience yet with National out of OHare. Specifically was wondering

1.) What gate(s) and terminal are they using?

2.) Can you check luggage Curbside?

3.) I have paper tickets, Can I check in at the gate or do I have to stand in line in the terminal to check in?

I read on the OHare web site that it is Terminal 2 but no mention of gate(s), is this correct? Wanted to get an idea of how early I should get there and how much a walk it is to the plane. Thank you for your assistance.
