Thanks for the advice on the Kissimmee station. I'm not sure we can change our departure location now, but will check when we check-in at the train station.
We are getting a lot of difference in rates between the various companies I've called ... one is $260 for 2 vans and one is $220 for 1 van that will carry all 14 with a pull behind luggage trailer. One other company is $412 roundtrip for 2 8 passanger vans. Some want full payment up front, others want us to pay in cash when they pick us up. Just looking to see if others have had any expereince with these companies.
