I'd like some advise on a road trip I'm planning with my kids ages 9 & 12 for spring break (first week of April). The plan is to drive from LA to Grand Canyon. What is the best/most interesting section(s) of the Canyon to visit? How many days should I spend in GC? Is it worth stoping in Jerome, Prescott and/or Sedona? Any other recommendations of what may be interesting for kids to see or do on this trip? I heard there is an interesting train ride from William to GC? Anyone have any info on that? What are some places not worth visiting? Thanks!!!
