I am trying to decide which towncar to use Happy or Tiffany. I have used Tiffany in the past but we will have 3 adults and 2 children and I don't know if all of us and our luggage will fit in the towncar. Is the stretch worth the extra money or should we ask for a van?? The rates are about the same and we will not use the grocery stop so we are mainly looking for service and how friendly the drivers are. Any help or comment s are welcome. THanks
