Camping it is not.  William and Kate will be staying at the majestic Ahwahnee Hotel.  The hotel will host the couple in the “Queen’s Room.”  Below is an example of the luxurious rooms at Yosemite’s “Grand Hotel.”

Nice, huh?  I’ve been to Yosemite many, many times and have always camped.  I can’t imagine staying at a luxury hotel, or can I?  In any case, I think it’s just lovely that their first visit as a couple to the States will be to visit California.
