The combination of Yosemite Falls being at its Spring time, full size with snow in the Valley is a bit unusual, at least for most of us who are not lucky enough to live there.
The site for the Ahwahnee, which first opened in 1927, was once a village of the native Miwoks. The term "Ahwahnee" has a confused history, but appears to have been the name the native Americans used for Yosemite Valley. It may translate more literally to "big mouth."
Even if one does not want to pay the price for a room at the Ahwahnee, having a meal there (breakfast is most reasonable) is something all visitors should do.
