In addition to all the great recommendations already given, there are a few good hikes in the May Lake area. The hike to the lake itself, and especially the views from the rocks to the east of the High Sierra Camp, are spectacular. Mt. Hoffman apparently now has an official use trail to the summit, although it invovles more climbing. Finally, a the loop between the May Lake and Murphy Creek trailheads is a nice walk, although a car shuttle might be needed. (Or... since the Tuolumne shuttle bus stops at the Old Tioga Road/New Tioga Road crossing that is just to the west of the Sunrise trailhead, and the bus will stop at the picnic area near Murphy Creek if you ask the driver, the shuttle could be used...)
Another fun hike in this area is an out-and-back to the tarns north of Tuolumne Peak--there are great views from the spur just before the trail drops to the lower tarn. Murphy Creek is the best trailhead for this, although those used to cross-country travel could get there from May Lake via the "May Lake Mystery Trail" (an abandoned but in excellent shape trail that heads north from the current trail north of May Lake just before it drops to the Raisin Lake area) and a traverse of Tuolumne Peak, which has similar views to Hoffman, without the crowds or repeater...
Also, following the Sunrise/Clouds Rest trail to the Sunrise Lakes junction, then heading west on an obvious use trail, leads to a great viewpoint of Tenaya Canyon and much of the northern Yosemite high country. The views from Clouds Rest are better, but if that hike is too ambitious, this viewpoint is a good destination on its own.
Oh, one more: from the Sawmill walk-in camground area near Saddlebag Lake, there's a nice use trail, with good views and an alpine setting, that follows a creek westward, past a research station, towards Mount Conness. Continuing past the head of this valley, requires moderate off-trail scrambling.
