We are planning our first cross country trip for this summer. It will be Los Angeles to Maine and then Back. We are planning on taking 4-5 days there, staying in Maine for a week and then 7-9 days coming back. I am really looking for any advice. We want to limit hotel stays, is it feasible to sleep in the car for a couple nights? Do you think we are crazy going there and back and only taking 3 weeks total?
