We are flying in to Vegas and thinking of driving through Red Rock then over to Zion(1 Night at the park entrance).What to do there for about 4-6 hours? Next day we drive to next GC and spend 2 nights on the south rim. Is a Jeep/Hummer tour a good call? Any other recs to do? We then drive to Vegas and Im thinking we would see Hoover on the way to Vegas. Spend 2 nights in Vegas on the strip and thinking of doing a Dune Buggy rental one day. Any recs on that or would you just go to one of the high end Go cart places and book that. Taking 3 adults with a 20,19 and 15 yr old. What should we look at for weather?We have never been to any of these sights or places. Thanks
