In reply to Richardhenton:
A couple of tips from a Valley regular:
- Whilst the rules on number of nights' stay are strict, there is NO SYSTEM for checking up between the different campgrounds.
- I've always given 'Camp4, Yosemite Village' as my accommodation address and never had a problem.
- With a bit of suffering in the queue, you can generally get onto Camp4 and no trip to the Valley is really complete with some time 'living in the dirt.'
Anyway, have a fantastic trip! For a bit of inspiration check out my blog from a 3-week trip at the same time of year in 2015
