I am planning a trip with my family (4 teenagers, age ranges from 12-19), we are active and like sight seeing stuffs. We are renting an RV on 8/14/15 and return on 8/22/15. I am open to all suggestion, we have not been to Vegas, would like to visit to see what is all the fuzz about but do not have a strong affinity to it so we can spend minimum time in Vegas. Also, would an intermediate 25' have issues while visiting Vegas? Do you suggest that we rent a van when we get to town?
