How bad will it be? Should we do Yosemite the last weekend in June 2014, and then SF July 1-4, or would the weekdays (Tues-Fri) of July 1-4 be better for Yosemite? Already have lodging in park for the June weekend. Due to work/school, this is the only time we can go - 2 adults & a 13 y/o.
Thanks so much!
