How Can I rent a train for 200 to travel from Miami to Atlanta?

I need a group of 200 people to travel from Miami to Atlanta on June of 2009? I tried to charter a plane and motor coaches but they are expensive is it possible to rent a train?

Contact Amtrack and Let them know you will be a large group traveling together. They will be helpful.

You can rule out Amtrak. The only train route they operate that stops in Atlanta goes from Washington to New Orleans, and doesn't otherwise connect with a train to Miami.

I don't think you want your guests to first travel up to the northeast before being able to travel to Atlanta.

Typically, the least expensive option is a bus. You may want to shop around a bit with various bus charter companies and see if you can get a better quote.
