We used TTC in November and had the van. It's a full size van - the kind with benches in the back - not bucket seats. It was me, DH, and our 3 children. We had plenty of room, but our luggage and stroller - well it all fit, but barely (I always overpack). It was definitely necessary for us to upgrade to the van!
We also did the free grocery stop. They stopped at Publix and picked up water, soda, snacks, and breakfast food for the week.
Hope that helps. Let me know if you have any other questions.
