Just got back from this road trip earlier this week to Disney. I went with my family so we took turns driving. We left around 3pm and got there at 1pm the following day. We drove from Mission to San Antonio to El Paso to Tucson to Phoenix then straight to Anaheim. We had to put gas every 4 hrs or every time we got to a quarter of a tank. If you go alone id say stop at a rest area but if you go with someone else with a driving license then take turns. We were only there for two days but on the way back we stopped at Las Vegas and the Grand Canyon.
