Help! I'm newly engaged and would love a fall wedding in Chicago. A lot of the popular venues are already booked because we are late to the game! Any chance anyone can recommend some venues for 300 people in Chicago? We are getting desperate.

Thank you!

Thanks for the tag @MobKaz
Newberry is too small for 300 people so is the Ivy room.
I would look at Harold Washington Library (my venue!) union station, field musuem, Adler (maybe?) chicago illmunating company, the rookery, carnival
Germania Place. It was huge and could work for you. But its an all inclusive type of place. Their catering, their cake, their flowers, etc.
Mid America Club (top of the aon building)
Hotels: The drake, sofitel, intercontintal, knickerbrocker, Swissotel (amazing views),
If you have fallen in love with a place and it is not available next Fall, I would really recommend moving your date. Most of your VIP (ie. photography and flowers) vendors are likely already booked for most of next Fall. Fall is the new Spring in terms of wedding popularity here.
The problem with a cruise is that no one canleave when they want to. You are trapped until the boat docks. And the food on those boats are always really gross
