Off to California next month, and still trying to finalise the last 4 nights and need some advice. We are lucky to have a free weeks accommodation in San Diego, we are then going to Las Vegas for 3 nights to meet up with friends, then have 4 nights in which to get back to LA to fly back to the UK. We want to visit a national park and thinking maybe the Grand Canyon South Rim for 2 nights,or 2 nights in different parts, any suggestions? We will then either drive straight to LA area or have an overnight midway somewhere and then a night in LA. Any suggestions?
