Hey Dave,
Thanks so much for your response!! This advice is exactly what I was looking for! Unfortunately 1 night is all we have for our Yosemite stay which really was an oversight of mine, we meet friends in both San Fran and Las Vegas on set dates and are staying with friends in San Deigo. Having looked at Yosemite and really gutted I haven't left us with more time as I know Im gonna regret it!!
Anyway, early mornings will suffice :)
Thanks
Kyle
