Hi this is our first time planning anything like this. We are from Ireland and hoping to go do three months traveling across America. Partly by car and partly in an RV. We both drive but one of us is under 25. Our rough itinerary looks something like this but is subject to change; Start in Miami and travel down Florida keys in hire car then back up to Orlando, New Orleans, Houston, San Antonio and Dallas, El Paso, Phoenix, San Diego, LA, San Francisco, Reno, Salt Lake City, Las Vegas, Albuquerque, Oklahoma, Kansas, Missouri, Chicago. We are hoping to do the latter part of the trip on some of Route 66 if possible. I would greatly appreciate any tips, advice and/or suggestions about any part of the trip including budget as I am really stuck here. We plan on having an RV for about a month and the rest in a hire car stopping off at budget motels and camp sites. We hope to go in early February 2008. Thanks!
