We're two Aussie girls planning a trip from SF to Vegas via Yosemite in April 2011. Any must-sees, must visits and should avoids (roads, places etc) and advice would be much appreciated. We have about 10 days (after doing the wineries of course) so plenty of time to see lots of great places. Is there a better road to take through Yosemite than others? How do we get to the falls also? (do these questions sound dumb??) Thanks!
