Hi, I would like to ask for anyone's assistance. My aunts and uncles are planning a roadtrip from New York to San Francisco in 28 days. I have volunteered to help them with this. They would like to see the sights along the way. They have drawn up an initial route covering the following: New York, Buffalo, NY (they also want to go to Niagara Falls), Boston, Washington D.C., Alabama, Kansas City, Colorado, Las Vegas Nevada, Grand Canyon - Arizona, Los Angeles Ca., San Francisco, Ca.
Will this be the best route considering that they would like to make stops along the way to see the sights? I am a bit familiar with the sights in California, Nevada and Arizona but I do not have an idea with regards to the rest that I mentioned.
I have checked initially with the car rental companies for a van that can seat 8 people comfortably (plus luggages) but the best car that I have seen is a 7-seater mini-van.
Any assistance will be much appreciated.
