Just wondering if a towncar will work for us or not?? Will be 2 adults and 2 kids (do I need a car seat for a almost 5 yr old) 2 lrg suitcases, 2 med sized a couple carry on's and then a lrg stroller... Will all this stuff and us fit in a town car???? We leave in a week and a half and haven't figured this out yet!
