I'm planning a very last minute four-day trip to the Grand Canyon with two eight year old boys. One would be happy to watch movies non-stop in the back seat, but the other whines all the way to Mammoth and is going to give a major hard time if we try to drive him all 7 hours to the GC.
So, any good ideas of activities/water parks/super-cool boy stuff along the way? A friend suggested we stop at Laughlin on the way up and get a hotel with a pool, which sounds good to me. Any ideas for the way back?
