to drive a long distance in an RV than a regular vehicle? Still trying to decide if we should rent one. Our kids'll be 5, 3, and baby (about 7 months old) when we go. I'm dreading the drive in our mini van with them, but is it really better in an RV? I'm assuming they still have to be strapped into their car seats, so I'm wondering if it will really make a difference or not? We have a portable TV/DVD player for our van and it does help somewhat, but we're driving all the way from New England, so it's a looong trip for kids. Last time we went we took the Auto train just so the kids would'nt be in car seats and could have some "freedom" and it worked out pretty good, but we were thinking about trying the RV route this time. Any thoughts are appreciated!
