My family (from the Boston area) - Mom, Dad and two teenage boys (ages 13 and 16) will be doing a trip up the CA coast in late June. During the trip we will be spending 2 nights (a Thursday & Friday) in Curry Village at Yosemite. Before Yosemite, we'll be spending one night in Mariposa. We leave Curry Village on Saturday morning heading for SF - so we'll have very limited time on Saturday morning in the park.
I've done a little research/reading about Yosemite, but am almost overwhelmed by the choices and haven't yet figured out what we should do for our 2 days there. Dad and older son are physically very fit and would likely be interested in some hiking on the more strenous side (moderate++); Mom and younger son would be neither willing or able to hike at the same level. Easy to moderate hiking better for us (I figure six miles roundtrip, assuming hilly terrain, would be our limit). Given the short time at Yosemite, and the altitude, all of us would want to avoid the most challenging and longest hikes.
As far as likes - we'd all love to see great views, one or two of the waterfalls, and Mom would like to see wildflowers (if in bloom then). Mom is a bit afraid of heights - specifically - don't like hiking that involves walking close to cliff edges, where a step in the wrong direction.... No problem with tops of most mountains (have done share of hikes in the White Mountains of NH); just don't like being close to straight drops. Also, the four of us don't need to be together the whole time, so a short but more challenging hike for the two more able would be fine also.
We're planning to see the Mariposa Grove - either on first day coming in, or when leaving the Park on Saturday to head to San Fransciso (ideas as to which would make more sense also welcome)!
