DH and I have planned a California itinerary/loop in a hire car taking in the coast, San Francisco, Yosemite and Vegas, and hadn't factored in going to see the Grand Canyon, but everyone keeps telling us to go and see it! I don't want to do one of those day tours from Vegas when you pay $$$$$ to see it for an hour - I'd rather go properly and spend the night if we're going to do it at all. I guess we are not that drawn to see it as we didn't plan to in the first place - we mostly want to hike in Yosemite and see the coast - so am just wondering if you think we'll regret it!
