In reply to Andy Hudson:
Within Yosemite Valley itself there is only the Ahwahnee hotel (have you won the lottery this year?) or Yosemite Lodge (Got your inheritance yet?). There are also the camping huts at Camp Curry (Good job required).
There is other non camping accommodation but it tends to be a bit further from the valley.
Basically, Yosemite is very popular with Americans and other nationalities, accommodation from camping upwards is limited meaning that it is all booked in advance and can be expensive.
We sampled the delights of the cocktail bar at the Ahwahnee hotel to celebrate after climbing The Nose and 2 cocktails were about £30.
Rich.
