Hi there, giving an RV trip as a Christmas gift to the kids this year. Already narrowed down, Flying into and leave from Vegas, renting RV from there. Will have RV for first 2 weeks of July 2016. Cclass for a family of 5 (3 teenagers, 15, 16, 18. I want to see Grand Canyon (and possibly horseback ride?) Brice and Zion? maybe ATV in one of those? not really sure what else or where else but want to be somewhere fabulous for the 4th of July! any and all suggestions are welcome. I heard about tracks and trails, but honestly can't afford the cost of their planning and need to put that towards the trip itself!! Thanks and can't wait to hear what you all have to say :)
