When purchasing tickets, there are no assigned seats, correct? Its general admission. So does that mean if we purchased separate tickets, we can still sit together?

General admission means that they will seat you, but the people in your party need to be together before seating.

Yes you can remember there is a two drink limit per person.

You can have assigned or unassigned. The assigned are the tables closer to the stage. You may have to share the table however you can pick your seat at the table.

After you get your tickets you will have a waitress that will take you to a sitting area so it's best to have everyone together once you get there.

Yes. You just tell them how many are in your party after getting in.
