I looked on the National website and it lists the 8 passenger Sienna as one of the vehicles that they carry, but when I check out the specific pick up locations, they don't list it as an option. We have 8 people in our group and wanted to save on gas and such with one car. Anyone rent from MCO area recently that has seen this elusive 8 passenger car? Also, could I reserve a mid size and pick this vehicle if it exists with my status from MP? TYIA!
