Definitely book a Hotel Room. Spending the night in Union Station, if allowed as the traveler mentioned, isn't pleasant!
New Orleans has plenty of Hotels, use one of the many travel sites ( Kayak,trivago,Trip Advisor etc)and find one that fits your needs and pocket book.
Remember the Crescent leaves early (7am)so youll need to be @ the Station no later than 6:15am the next morning.Having Breakfast in the Diner while crossing the Lake on the Causeway is the Highlight of this Route.😎
