I'm travelling around California and to Vegas for three nights in June with 13 yr old son. Definately want to see grand canyon but we won't have a car or lots of time. I realise west rim is not the real deal but would still like to see as I believe this is the best we can do. By helicopter as son would never make the hours in a coach, seems very expensive. Found deals online for £410 for both of us to land in the canyon and see hover dam and strip on way back. Is that a good deal or could I get it cheaper once I'm in Vegas?
