We hired an RV last year and played pretty safe with stops in Yosemite, Vegas, Williams, Anaheim, Pismo and Santa Cruz. We loved Yosemite and The place near Santa Cruz (within a Red Woods area). Anyway, we are coming back again in 6 weeks time (late booking I know!) and struggling to figure out an itinerary - we will have a 30ft RV and there 2 adults and 2 teens. We collect and drop off in Vegas (we stay a week in Vegas after dropping it off), our initial plans were to go to Utah and do the big 5 but for several reasons we've scrapped this idea. We are possibly going to do Zion as our camp ground is already booked. So our loose idea is the Valley of Fire State Park (although I believe you can't advance book which is unnerving!), possibly Lake Mead but all the info I can find is not really to our taste - it seems very commercial. We love the natural places with comforts such as full hook ups and shows - a pool if possible but not essential for 1-2 nights. I'd love to stay on sites that have streams or the side of a lake, where you can relax, possibly swim, wade or kayak (hire). We are then hoping to head to Zion for 2 nights. From here we are a little stuck but we want to end up in either LA or San Diego or somewhere in between for about 4-5 days, again a beach side or close by to a beach location would be great. We may hire a car while in this region. In between my husband mentioned Mojave but the videos I've seen don't entice me - it's June/July and it'll be boiling hot and it seems to just be hiking/long walks with no shade or facilities. The maybe Joshua Tree?!?! We like to be on main sited areas or with good transport links (eg. Springdale to Zion) as we don't have a car with us (as we are overseas visitors). Our dates are 18th June for 14 nights. Any suggestions for itinerary or parks? Thank you in advance for any assistance offered!
