My mom and I want to drive from Boston to Los Angeles this weekend (one way). Because of limited time (3 days), we'd like to take the shortest but also the warmest route, because we are also concerned with the weather. What would be the best route to take and still make it in 3 days? This is our first time so we have no clue which road to take and how to make the best out of our trip. Advice needed on where to stop and where to stay on the way? We are leaving this weekend and will appreciate any suggestions. Also we will be driving an acura integra (6 years old). Do you think it's a good idea ? We do have AAA but besides what could be the problems we may have with the acura along the way?

Thank you in advance for any advice you can provide.
