We have reservations for round trip with Tiffany Towncar, but using a van instead of the towncar. I called and was told that the towncar might not have enough room for 2 adults, 2 children, luggage, stroller, plus groceries from the store stop. We used the towncar on our last trip, but just for return trip to airport. Any used the van before? Is it nice? I'm just worried that the van might not be the same quality as the car. If anyone can ease my mind, I would appreciate it.
